Oh, I just tried latest version and now it works fine :3
I can finally play it, yey!
Game looks fun. I guess currently you can't speak with NPCs yet (or can you? I couldn't or I don't know how). Level itself wasn't too challenging for me (I was able to finish it on the first try), but that's probably only some start. Controls seems to be pretty solid, I haven't had any issues with that.
I hope to see how this project will grow and wish you all the best with further development ^^
