Absolutely awesome game, didn't stop playing until I beat all the levels. I will say though, a lot of times when I fail, I accidentally hit a key that leads me to either retry or go to main menu. Like, I'm hitting a key to try and press the right button, but then the timer runs out, and I accidentally hit retry or the menu instead. You should probably make the retry and menu buttons binded to something else rather than WASD or the arrow keys.
