Thanks for the feedback! :) It was my first time experimenting with lighting, so your comment really means a lot ^^
As for the bug, I think I found the cause… I bet you opened the options menu before playing the first time, but didn’t open it during your second run. :D Basically, I think the keybinding buttons stay active even when the menu is hidden, so when you played, you might’ve accidentally changed the controls without realizing it. At least, that’s the lead I’m following.
