oops i nearly forgot! i still enjoyed the game - cause i am down that bad - yet, it kept on glitching and background flickered black, just so you know! again, thank you for feeding us so good, i was never sad.
for the background thing, try holding shift upon clicking to open the game (but before it's actually opened) and picking the 'force angle2 renderer' option. it happens on most ren'py games for me unless i do that so i figure it's my laptop lol.
