In case it helps, I also got the freeze (the platform was rising fwiw). Restarted then got the freeze again, both on web. Played the download and made it to the end. Both times it froze right when I cast time.
Thank you, this was helpful, I was able to reproduce the bug now! It seems like its specific to the browser version which is why I didn't catch it - theres some kind of crash related to playing the enemy's sound effects, seems like it's caused by trying to unpause their animation at a specific point. Will see if I can fix this for a postjam update.
