Hello there. First of all, I'm awfully sorry for the suuuuper late reply, I don't get notified when new discussions pop up here even if I asked Steam to tell me. Strange.

Anyways, you're right, it's not normal ! But sadly, I kind of dropped this game because almost nobody was interested in it, and I couldn't see how to finish it and make it profitable. If one day my other games are successful enough, I'll try to finish it pro bono. To begin with, this game was only supposed to be a present for my nephews...

Sorry then :(

You probably have 4K display like I did, I changed Windows resolution to 1920x1080, then launched the game and it works
