Hey! It seems the browser is running out of available memory. What are the specs of the device you are playing with? Right now I would recommend playing with the desktop version.

I believe what I am playing is the Desktop version. I installed it from the itch client, but the window does seem to say something like Web Player when I open it. I have a pretty good PC able to run very demanding games so I don't think it is that (will reply later with some more specific specs). I will check if it is the browser version, and try to download it from the web and not the client and update you
