Wow you truly are the bounciest bug! I'm impressed, I think I got up to around 300 once while developing that's why I added the message, but I didn't think 342 was possible.
Yes the comment section seems to be good as a score board for now, I'm not sure how best to implement that either, usually when I've done it before I used the google play services APIs to log the score and then they manage the rest... Maybe something like that would be nice for itchio in the future too.
