Thanks for playing it :) I tested the HTML5 build and it runs fine (you can remap etc.) but itch.io embed is a bit wonky (two times already it seemed like the keyboard wasn't responding). There's also the HTML5 build hosted on my server. I think I will just delete the embedded HTML5 on itch.io and leave the link for my server.
Anyway thanks for trying the Windows version! hope you can reach the leaderboard :)
