Thanks for telling me. Will try to fix that soon. Sorry you couldn't finish the whole thing - I did test it, but bugs have a way of slipping through. Could I ask what browser you were using? It worked for me when I was testing using both Brave Browser and Firefox.
Edit: I've tested the game using Firefox, Brave Browser, Opera Browser, Microsoft Edge, and Google Chrome. I couldn't recreate the error. I'll have to put the bugfixing on hold, since I can' t exactly fix a bug if it doesn't show up for me.
