Not working for me :< Did manage to figure out that you have to run runme.bat (Itch client hasn't got a clue what to do with it!), but can't get any of the controls you listed below to work :<
This is my first game uploaded to itch, so haven’t tried getting it to work with the itch client. I think I have to wait until voting is over to fix that.
I guess next time, I’ll have to test it on a fresh PC after uploading.
