UNDERFELL - Instructions in-game. Note that this game doesn't feature saving, you you better have like 2 hours to spare. Or not, and you just want to see the horribleness of it so far. Feel free to remix. However, I ask of you to turn it into an UNDERTALE AU game (NOT UNDERTALE itself, because I'm gonna work on that).
UPDATE LOG: V0.1.0 - Release. Not much here, so if you want to play UNDERFELL, play something different. V0.2.0 - Hardly anything added. A tiny bit? V0.3.0 - A bit of totally out of sync music
