Undertale: Dash Mode

A Geometry Dash-style dodging minigame inside Undertale battles. Reads Stereo Madness from your own Geometry Dash installation, patches a copy of your Undertale data.win (your original files are never changed), and launches your own UNDERTALE.exe on the patched data.

Solo play. Requires Undertale and Geometry Dash (both via Steam or standalone).

First Play prepares the level from your Geometry Dash and takes under a minute. Hold Z, Enter, Space or Up to jump during the dodging part of any regular monster's attack turn.

Built with UndertaleModTool (GPL v3, UnderminersTeam).
