I saw your falling sand game vids, which by the way have been a great inspiration, and I've been making my own since. I really enjoy seeing the progression of regolith and am stuck in anticipation for every upcoming devlog.
Do you mind me asking though, why you stopped? I'd love to see you make (and teach) more mechanics for falling sand games, for which I have quite a few in mind: explosions, particle velocity, "timed" cell behaviors, etc.
Although truthfully I have a good idea of how to make these effects and have even seen other creators do it, but it would be interesting to see your take on it.
