I found the projectiles coming from the left-hand side (as supposed to the classic right-hand side) a bit confusing and they were too fast to dodge. I also discovered occasionally you didn't have to do anything to get to the end because the ground didn't change height and projectiles didn't spawn in my direction.
I'm a bit upset that the game logo didn't indicate the type of game. I thought I was going to be playing with a pixelated, burning mouse cursor :(
