Nice to see the game from the Twitch stream ;-)
Oh man, it is hard an all progress can be wiped out quickly ;-). Fun and definitely worth to check out. You put a lot of effort in making it.
I had a problem with a web version. I got a pretty much a freeze, although I was able to kill the tab. Checked on: MacBook Pro (15-inch, 2018). Maybe would need to check with all stuff closed another time.
Then I downloaded a Windows version on some older laptop and it worked fine.
