Description (written by the developer; not a statement by this register)
A project made for fun. Disclaimer: ! This game is still in BETA! A lot of things may or may not have been implemented into the game, since it is a solo developer who is working on it. Credits to: NikoLander and A_RandomDoggo for creating this UTMM Kit, and lastly credits to Toby Fox for making the game "Undertale". Credits to the creators for the models I used in game, I do not own any one of them.
