If I had just a little more time, I would've loved to fix this, among other things. But with itch.io's servers already beginning to wobble dangerously, I figured it best to let my finally working and uploaded build stand as it was and let others upload their projects rather than try to jam in more frantic bug fixes in the last minute while everybody else tried to upload as well. Glad I did, because the servers tipped over soon after. Anyway, I'm rambling.
If that's the only thing that bothered you, then I guess I should say Thanks! Happy you enjoyed it. I think clicking the little FullScreen button in the bottom right can help this issue for others who might experience it, but of course as devs love to say, on my machine, it looks fine. Cheers.
