"Forget about grinding or locked content — everything is available right from the start. From vibrant fish to countless decorations, you’ll have every tool at your disposal to craft aquariums that reflect your imagination." I think this alone is why I can't recommend it - It truly feels like they gave up and just released a basic creative mode. The bones of something unique and awesome are here but they are asking way too much for whats on offer. May get it again if it pops up for half price.

AMAZING!!
i dont want to be too harsh about this & i might well be totally missundersdtanding or missing something but to me this is like a modern version of one of those old interactive screensavers where you can choose what fish & add coral etc. okay so i think it is me not knowing what i am doing. i couldnt find any corals anywhere but i think that is because the game gives you a freshwater tank at the start i dunno im confused brb. so i went for the design mode which is the unrealistic mode as in not the simulator mode. i see now that the simulator mode is very detailed with everything you can think of for water settings ..ph levels ...tons of that sort of stuff. also in sim mode you have to consider fish compatability. i hope it has a tutorial for sim mode so you dont just have to guess & learn trial & error. i would love this if it did have a game mode where you had to level up to unlock & learn the bext thing...this would make a great turtorial & gaming mode. i know a lot of people dont ...
(Google Translate) This is a great game. You can really tell it was made by someone who loves fish! What I particularly like is how the habits of each fish are portrayed in the game. It's so beautiful, it's almost like looking at a real aquarium and its fish. And yet, the game makes it so fun, allowing you to easily do things that would be difficult in real life, like creating live rock in your favorite shape and breeding fish! There are so many different types of fish, and the jellyfish I purchased are beautiful. I'm very satisfied, but personally, I'd love it if there were rays like Potamotrygonidae and Hemitrygon akajei. I especially want to see Potamotrygonidae swimming with Arowana and Datnioides! Thank you for a great game! Of course, I recommend this game to anyone who loves aquariums.
