Pretty clever idea and fun game, some of the challenges seem a little too difficult in the beginning. The combination of the 2 hazards in particular. I think there may be a memory leek there too because I got a massive slow down in that section and the projectiles started to bug out. I like the idea for the game, one button. The character had a meatwad vibe too, haha nice job.
There is a known bug that I easily overlooked before submitting. Usually, for testing purposes, I program my games so that pressing the escape key will exit the game. However, the code I used to exit isn't compatible with the browser player and causes some memory issues. That might have been what you were experiencing.
I'm glad you liked the game! Thanks for all your great feedback.
