Oh, I've seen that error happen with macOS and Linux on the web version. Can you tell me your browser, operation system and if you are running on a 32bit or 64bit CPU? I might make a Linux build in the future.
i don't know if you should worry about it really :\ -> i was using Waterfox. just opened your game in Chrome on my computer and it worked just fine Edit: but otherwise, Windows 64 bit
