MYSTERYTALE Online is an fangame based on UNDERTALE by Toby Fox. There are tons of skins to mess around with and even a PvP mode to duel each other in while exploring a lot of maps from the original game!

Hello, I've been banned from this game for a bit and I honestly don't know why. I haven't been on for a while because I've been trying out other games also, so... yeah.

Howdy! I'm just leaving this message here in case if someone has met me in [Mysterytale Online] and wants to have some sort of contact through GameMaker Server. Sometimes I add people in the site from fangames I play. Hope that anyone I once addressed to contact through here will see this message!
