Got a pretty big update, and it's that I think I somewhat killed the L-A-G present on the Overworld (especially in late game). I've also fixed up a few passabilities in some areas, and I believe I fixed the whole post-game bug-whenever-entering-moon-caves-thingie. I've posted a new download for the game with these new updates (Google Drive) so I hope you'll take advantage. Oh, and you'll want to start a new save for the game after downloading this updated version. Old saves will work, but they'll be all wonky when going back and forth between Overworld and towns/dungeons.
Here's hoping the game performs better, and thank you all for your support! =)
