"performance mode" doesn't seem to work. i click it, and then press "back", and then go back in and its unchecked again. i even pressed it, save & exited, and still, not checked. not a huge issue; i just had a tiny bit of lag at the end. just thought i'd bring it up in case someone else's computer explodes from too many coins. (exaggerating, but, you get what i mean hopefully)
overall, VERY fun game! took just under 20mins for me to complete. love the concept and the art style. definitely reminds me of this weird flash game ( that i can never remember the name of) from back in the day. very similar vibes, its nostalgic but also new. y'know?
