Love the game! It's a great combination of laid-back and addictive. It's part puzzle game, in that you need to pick the right shape, time, and location to get the best reaction. When you hit a wall in progress, it allows you to upgrade what you began with, helping you to pass stages that were truly impossible to start. The initial minimal design gives way to a fireworks show of color and shapes as you progress, and the pace of that progress is tuned just right, IMO. Overall a great game!

This game is challenging and addicting! You begin with a couple shapes that each have their own mechanic (circles do an AOE, squares shoot in a line, etc). You try to use these mechanics to hit the other shapes on the level and do damage. The more shapes you clear the more points you get which you can then use to upgrade the shapes. Once you upgrade the shapes you can replay levels you didn't complete to improve your score which offers a ton of replayability. I really enjoyed how the game mechanics and sound design work well together. The shapes take damage to the beat of the music and it makes it even more fun to play with sound on (something that most other mobile games are lacking!). I really enjoy this game and am about 50% complete at the moment. It's well worth your time!

Great game, great pacing, loved the music and upgrade system. Only played the Easy mode but it was very satisfying. I wish that after completing the full mode, there was a way to rank 9 all shapes and go back and play with true max upgrades. Just for fun. Ads aren't too bad, but watching ad for level increase doesn't seem to actually restart ad timer. Pretty frequent, but not invasively so
