I liked the health system, because i hate when I lost after just touch one time the obstacles, but the sounds, the low mobility of the ball and the absence of music makes this game pretty boring.
Keep updating it and it will be pretty awesome!
Maybe add more Sound, or background animation? And whats about Music?
Sorry, not very good, its just too simple to be fun, the things are always the same colour, also there's no music, and just 1 sound, and blocks are too big. Try better next time
