Oneiro is a challenging rogue-like, similar - but different to - risk of rain 2, that gives you creative control over how you want to play. You can be a tank with lots of hp and health regen, or be a speedy boi with 10 mid-air mad hops. The thing that makes this game so incredible is the duplication mechanic; where you can pick up 'duplicators' and use them to create a copy of any item in your inventory, making you stronger. Oh yeah, I forgot to mention that this game is very unforgiving (in a good way), so it's great for people that like lots of replay-ability, and those that like a challenge. I have sunk nearly 24 hours into this game at the time of writing, and this game has me hooked. This is a good game, with a cool developer, and I can't wait for future updates.

About This Game

With your mind saturated with horrors from your caretaker, venture to the depths of your nightmares to overcome your fears.
Lucid Dream the 4 Layers of your Labyrinth to reach the end. Each layer gets progressively more difficult and is meant to test your knowledge of the games mechanics. Collect/duplicate items, find powerful weapons, and use gear to conquer your Labyrinth.
Choose a Weapon
Fists, Swords, Karambits, Hammers, and Spears. Out of these, players will be able to find a weapon that suits them the most. Each of the weapons are unique in their own ways, and diverse enough to keep combat fresh and engaging.Get Creative
Oneiro allows your creativity to shine at any given moment, and nearly every object and mechanic have multiple purposes. You may want to go right up to an enemy to fight them; or perhaps you'll want to use throwing knives to destroy a nearby wall and collapse the ceiling onto them; maybe you'll break through the ceiling and attack them from above.The Power Behind Items
Items are normally found through treasures, and they play a major role in Onerio by improving the players stats, or granting new abilities. All items can be stacked to multiply their effectiveness, as well. If the player wants to focus their duplications and have 10 midair jumps, or regenerate 20% of their life every 10 seconds, or even causing enemies to explode in a large radius upon death; nothing is stopping them from it.
The "Rogue" Aspects of Oneiro
It's important to clarify...There is no progression in regards to gameplay. The only thing that'll change between your 1st run and your 100th run is your knowledge and skill with the games mechanics and systems. There are no permanent upgrades, nor anything that will persist between runs.
This game is meant to be difficult but fair, and despite the Labyrinth being randomly generated with each run, you'll notice some subtle patterns and some tricks to help you get around the labyrinth quicker and safer in your future runs. This "learn-and-adapt" loop is what separates a new player from experienced players.

- 50+ Equipment/Gear to discover and utilize
- Stack & duplicate items to improve their effectiveness to no limit.
- 20 weapons split among 5 weapon types(Fists, Swords, Hammers, Spears, and Karambits)
- 4 Layers of your Labyrinth to explore and conquer
Oneiro also has control bindings, full controller support, as well as Steam Achievements.

Parents have resorted to telling their children horror stories to keep them in check. If a child messes up, they'll formulate a horror story and direct it towards the child specifically. Despite being considered inhumane in some eyes, these parents saw it as a solution to their children's behaviors; ignorant to the psychological damage they were causing them.
These children eventually find themselves at The Island- a remote location thousands of miles to the nearest shoreline. The victims stay at this island until they get over the fears that their caretakers gave them. Once they inevitably go to sleep, they find themselves dreaming up a Labyrinth- a congregation of every fear.
Only by conquering their Labyrinth, will the victim be able to return home.

User Reviews
Oneiro is a first-person roguelike action RPG featuring rock-solid gameplay, dead-serious challenge, and a shocking amount of extremely clever and effective design decisions. It's honestly one of the best games I've played in years. If you love roguelikes, King's Field, Morrowind, or just good action games, at this price it's an absolute must-buy. Its core combat is fundamentally well-designed because all damage can be avoided through skill, although doing so is easier said than done. There are several weapon types, each of which features primary and alternate (usually charge-up) attacks. Special mention goes to the default fist weapon, which has several alternate attacks depending on when you right-click during your auto-combo. The traps, enemies, and bosses all do a phenomenal job of capturing the "look before you leap" gameplay that was so successful in CastleVania and Dark Souls. Namely, the best way to play Oneiro is to proceed carefully and keep your eyes and ears open. New pla...
I'm not too far in, just kinda getting my grip around the edges of the gameplay at the moment. There is a nice balance being struck with the gameplay systems, Each time you re-enter the dream the combat becomes a little more clearer, and you're ability to read telegraphed attacks from the enemies broadens. As well as this i'd like to mention the duplication system, A truly awesome videogame mechanic, subtly implemented into the gameplay allowing you to duplicate any item you want. This allows you to stack abilities like the double jump, essentially letting you jump all about the place like 'Jumping Flash' So yeah don't be fooled by this games simple art style, as there is a deceptively deep title here with plenty for any fan of the roguelite genre to enjoy.
A nice breath of fresh air, challenging experience and great fun. Definitely worth the full five dollars, with an interesting concept and neat mechanics. You can feel the love put into this game and see the developer is showing how much they care about their own product, getting direct insight from Discord and their friends about bugs and suggestions. I recommend playing this, five dollars isn't enough to repay the joy from this amazing game.
Honestly one of my favorite indie game of all time. I was never a fan of rogue likes until i played this game. It is challenging but not hard for the shake of it. You can actually learn the movements and attack movesets of the enemies and improve in the game. When i lose the game, it's almost always my fault and not the game's, and i learn from those said failures. It still has some problems which the dev addressed and said will fix/improve in the next following updates, which shows that he still tries to improve the game for us to enjoy. If you are up for a good fun challenge definetly buy this game. Definetly worth your time!
Disclaimer: My actual play time is about 15 hours and I have only seen half the game. Yes it’s difficult but in a great way. Oneiro is perhaps the very definition of "greater than the sum of its parts." On the surface, it may look like something you've seen or played before, but underneath... Ah... Underneath... There is something beautiful to the "nightmare" of the labyrinth: a transcendent quality to the game wherein its dimensions coalesce into something more. You might say, "What TF is this dude on?" Well sit down and let me tell it to ya mostly straight because this game hooked my apathetic @ss like a grappling hook in a flying spear. What you get with Oneiro is a lovely old-school, "crunchy" experience with newer features as well, all encased in a design philosophy that respects player learning (no metaprogression) and player freedom. It has solid melee combat with different weapons for different playstyles. The weapons also have variants by tier which sometimes changes thei...
I got this game because a friend told me they thought I'd like it, and they were spot-on; I'm really enjoying this game! No two runs are the same, I feel compelled to explore different strategies every time I enter the Labyrinth, which seems great for keeping me engaged. The Labyrinth randomizes every run in structure and enemies, and you start each run with the same thing every time (your bare fists, with a satisfying knuckle crack); but as you play you can collect different weapons, power-ups, and consumable items, that make each run unique. I especially love that the power-ups stack seemingly infinitely. In one of my runs, I stockpiled 13 of the "Midair Lamp" power-ups that grant you an extra jump each; so in that run I was basically flying around the place, it was FUN. But there are loads of different power-ups and combinations to try out, and if you're enjoying a particular power-up, the Duplicator item is fairly common and lets you choose a power-up you have to get an additional ...
Really fun game with cool item, enemy, and weapon design. got a great gameplay loop I'd say, go into labyrinth get items/weapons fight boss with each different arena's and style of fights only getting further by getting better/not being a reckless dipshit like I always am lol. Story isn't bad either even though it isn't the focus of the game it is still real cool to learn about the peeps on the island and their fears. all in all its a fun game and for 5 bucks it is 100% worth it imo.
Edit 04-16-22: The controller support has gotten really good. Both my controllers work, and the turning/aiming is really smooth now. I also appreciate that you can rebind the buttons, but I think you could already do that before. This game is not for me, because it might just be too difficult for me to really enjoy, but I do think it's a very interesting game that some people will absolutely adore. It reminds me a bit of Spelunky in that regard. Positives: - Interesting premise; - Good atmosphere; - Breakable floors/walls; - The use of a grappling hook; - Melee combo's. Negatives - Difficulty (for me); - Wisps look similar to projectiles and can move through walls, which makes me on occasion unaware of their presence.
I would say after playing and beating this game I would Highly recommend this Game to anyone who like rouge-likes. It's confusing when you first boot it up and offers next to no explanation for how things in the game work. Which is perfect It allows the play to kind of grow and figure this stuff out. (at the time of creating this the creator did make an optional tutorial.) As it stands now the game has replay value is small and is beautifully simplistic. I would Highly Recommend
