The game is kinda cool, one thing i noticed that is kinda annoying is that jumping also moves the camera, what means that if i jump, the floor gets completly invisible, including obstacles, making it very hard to sightread the game (as you mentioned gd, think a map pack level that every click is a blind jump).
Also, as someone that have a bizarre desktop, i needed to use virtual keyboard to press enter every time i died. Maybe adding other key to start the level, or button in-game?
