I started with the example puzzle template, but I tweaked it a little to add more blocks etc.
What combination of physics settings, bounding boxes seem to work the best to prevent any sticking while falling? Given the blocks are right next to each other. Should I just move them a pixel over?
Any advice is appreciated :D
Update: Here is an example, the brown block should be falling down. But it is stuck, when a new block falls on it, it will knock it down I think.
