I'm not sure why you had a crash... We tested it on multiple PCs, via direct download, and with the itch app. We haven't seen crashes ourselves. I assume that you are trying to run on windows?
Ah! It could just be very slow loading... we didn't have time to optimize the scene load where the procedural generation happens. It takes about 5-10 seconds on my local machine, but I could see it taking longer on some hardware.
