Can't get a world created! It says "App can't open this 'itch-cave' link" when I press Create to create a world. Hmm. Any way to fix that so I can play please? :)
I tried fighting itch.io's iframe for a while, but it just always finds a way to clobber something important (especially on mobile).
So until they give a better option, I've removed the "play on itch" option. The game works better when you play it from valtima4.com, so that's the officially supported way to do it now.
