Hm... that's my fullscreen. So I see no UI at the bottom. WASD make no effect...
Thanks shov for pointing this out. I enabled scrollbars as a quick fix. I try to make to make the resolution smaller as it does not seem to scale properly to the browser size. I will post updates when I get the fix released.
If I change the browser scale down to 67% it's playable :D
Can you try now? I uploaded a new version fixing the resolution.
Fixed, thanks!
