Incredible. You've hit the perfect sweet spot between unique mechanic, satisfying level design & progression, theme, and frustration, while also keeping the game remarkably simple, intuitive, and accessible. It can technically be played with one finger!! Fantastic physics that aren't overly bouncy -- the way the player knocks off of obstacles is just right. The only things I could possibly fault this game for is there could be slightly more friction when the player grazes the ground, and also that the mechanic has been seen before -- minding that it's played up to amazing standards in your game. I felt all emotions ranging from curiosity, excitement, anger, amusement, determination, and finally despair (when I gave up) when playing this. The long soundtrack suits to immerse the player further and is a delight to listen to, regardless of whether or not it's stock music from somewhere (I have no idea). If I had more time tonight I might try to beat it but I have no idea how far up the rabbit hole goes. I got stuck at this innocuous-looking but extremely small pinpoint ledge somewhat above the wall-breaking area, and if you miss you have to redo like three challenges. I'd love if you told me what percentage of the game I got through if you understand the area I mean. I'll go out of my way to recommend this to others and I highly suggest you release it on Steam at some point.
If you're reading this, play this game!!
