I'd like to report a bug. I like to use my Xbox controller for VNs and it works fine, but for this game it causes it to crash. Even literally just touching the controller would make the game completely crash to desktop, most likely from the slight movement of the analog stick, I guess. Anyway, from looking at the traceback, I actually found the problem.
File "renpy/display/behavior.py", line 242, in map_keyup if (name in ev.eventnames) and ev.up: NameError: global name 'name' is not defined
If you change "name" to "keysym" it fixes it and the controller works.
I don't know if anyone else encountered this issue, but I hope it helps.
I really like the work you guys have done with this game. The story, characters, music, and art really shine and the amount of talent and hard work you guys put in is clearly evident. Keep up the great work!
