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!

Really good game, very satisfying. I just have one thing for the developer(s), if they are reading this, the square and star's hitbox can be buggy sometimes, for example I triggered a square that was going to hit a circle Infront of it but there was a gap between the square and it's beam so it missed, if you could fix this I would love this game even more. Thanks

I am glad you are enjoying the game HyperLV! The gap between the square and the beam is actually an intentional balance lever I pulled because baseline squares were heavily outperforming other baseline shapes. I tried a few other options but they all felt even worse to play with. I am looking into the star hitbox thing, that isn't intentional.

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!
