I wanted to make this game playable in browser, but as it turns out, exporting games to HTML5 is arcane eldritch magic that is not available to such mere mortals as me (it's complex, frustrating and I couldn't be bothered to go through that right now, so pls take your exe and be happy about it x_x)
