not fun. the game has a nice ascetic, but it is 100% luck based. and not in a fun way. It's just frustrating. there is no skill or reasoning to the levels because there's too much going on. you pick a random place to press and pray. the upgrades aren't satisfying, the hit boxes are frustratingly jank, and the tutorial pop ups aren't very helpful. Just frustrating, not fun. dont waist your time.

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.
