Well, I have an idea, finally… it is basic but in my head it seems to be playable and fun!.
The concept is, you control a ball which is over a board. You have to make the ball reach some part of the board through a hidden safe way that you must discover. The board is composed by blocks, some of them will begin to fall apart when touched by the ball, you have to move the ball away before is too late!!
I have not too much ready yet, but I believe it could be fun, here is the latest version (very incomplete and very unstable, so it could be not working right now).
I am recording a time lapse too, if I finish the game in time for the compo, I will upload it to youtube or something.
