Version 0.9.6


  • Fixed an issue with the settings menu when a controller was connected.

  • You can now choose whether the Auto-Shoot button must be held or toggled.

  • Added hell hard mode in the settings, which reduces your own stats, and increases stats of certain monsters. "No human has ever made it past Asgore."

  • (Two of) The Steamworks rooms have been improved graphically.

  • EDIT: Nerfed Asgore in Easy Mode

As always, if you find any bugs/glitches, let me know!
