Being unable to recover after you hit a purple surface is insane. Kinda like Flappy Bird level difficulty.

Amazing job at on-boarding a new player. The game concept was excellent and super well executed. My only complaint being that the game scales in difficulty _very_ quickly. But it's a great idea!

That roll of shame when you hit a wall is ice cold! Great use of simple shapes and background music, although the constant sound effect when moving made me have to go on mute after a bit. Great tutorial section to show how to move without words!

Man that's brutal :D

Really cool! The visuals are really cute. It was a bit hard to get through levels 2 and 3 though. Also liked the background music but it was a bit too quite compared to the soundeffects. And also some optimizations regarding the controls could be made, it's currently not possible to press up and left/right at the same time. 

The face expressions of the ball and the music had me smiling the whole time. I played in a very safe and slow manner because I couldn't see the walls coming. I suggest having the camera show what's ahead of the player to encourage faster movement. An instant restart button would've been nice too. Good work!

Feel like this could be a cool mobile game!
