Cool concept to kill 2-3 hours on, with a LOT of bad design decisions and a flat difficulty curve that never picks up. 1. It should be a crime to make a game as simplistic as this not have mouse-only controls. Not only that but the game has the audacity to suggest using arrow keys, spacebar, AND the mouse. Put your hands on those keys. Do you realize you would need THREE hands for that? Thank god WASD input is also accepted. 2. You must solve every level under a limited number of moves but this is never explained or mention and you will be seemingly randomly failing some levels until you find it out. 3. Levels have a timer as well. In most cases it's like five minutes which is comfortable enough to not care about it. Some levels don't have a timer at all. But then one level has sixty seconds for instance. Like... Why? It displays a game over screen, you click the Restart button, and continue staring at the same level still looking for the solution (which you then do in mere seconds...

Definitely made me think.

A short game with 50 levels of math puzzles and only one solution for each level. I enjoyed it although the game is short and only requires basic addition and subtraction mechanism.

Very nice math game, it's simple or not, i liked!

Great puzzle game, with a interesting mechanic. I recommend it.

The rules are never explained. I've played for 20 minutes and still don't know what I'm doing. I'm done. If there were a tutorial, or even if there was a block of text that explained the rules it'd be better. I would not recommend this game.

Simple puzzle game, sure, but it was fun and I did enjoy my playthrough. 50 levels is a tad bit short and I did accidentally restart a couple times, but overall not bad for a quick puzzle fix.

I loved the game. It has a cool and challenging mechanics. Perfect for math lovers. I recommend!

How I wish my school had a game like this when it taught algebra. It's so fun to add and subtract numbers when you have a rewarding atmosphere! Very cool game, a must get.

A very good and polished game.
