• Nice work, Jason. I enjoyed a lot a talk [1] at GDC by Petri Purho (Nolla Games and before that Kloonigames) that explains the "Falling Everything Engine" used in their game Noita (that I would love to play on my mac...). Highly recommended if you …

• Thank you! If you haven't played Noita it's basically a "falling sand" or powder physics game where every pixel is simulated. You need a special cellular automata that is not your typical game physics engine, so I don't think Babylon.js would be a good choice …

• Thank you! It's funny because I really wanted to introduce more things like that, but the very simple things I've added so far have received a bit of pushback ("I want to play a factory game, not solve puzzles!"). So now I'm reconsidering it, but …
