Underbattle is a game engine made in Game Maker 8.1 (and Game Maker: Studio) based off Toby Fox's Undertale!
The engine was built from the ground up with original code except for the textbox, which was modified.
Much more well-documented than other Undertale GM engines.
All character (objects) can function as both either as the player or monster in battle.
Extensible menu system for easy modification.
Unlike the original, completely playable by mouse/touch!
