Click on the battle buttons to use them. Use W,A,S,D or the arrow keys to control the SOUL. In a menu, press X to exit the menu. Please, PLEASE when pressing buttons, wait about 1 second after Gaster finishes his attack. If you don't it will break the script and cause the whole game to work incorrectly.
When at the choosing scene (FIGHT or MERCY), DO NOT click the buttons. Run into them with the SOUL. Credit to Toby Fox for Undertale Credit to The Great Anansi for the Gaster Theme remix This is probably my biggest (and best!) project. I'm really proud of it.
