I'm so torn on this game, at moments it can be a fun time, but most of the mechanics and the overall level structure is so unforgiving that you NEED to play with save-states in todays age. Whenever you enter a room and don't collect the star and accidently leave the room the star disappears and you have to do the task over from the start again. With how easy it is to easily leave rooms its nothing but a chore to get through. There needed to be more mechanics to help us traject where we want the ball to move because there simply isn't.
A fun concept, but maybe if more thought was put into it then it could've been something special. Ignore this one if you want.
