1. need a better tutorial, do not put everything in first few level and make player to only learn and wait, can't play, so, make a playable tutorial next time

2. need a better level design, until level 22, i still not see any smart use of bounce ball and ice and red zone

3. the worst thing is, level 22 make you wait like forever, i would play antimatter dimension instead of this game

the only good things is physic in factory game, that why its not 1 star
