DON'T WANT SPOILERS? STAY OUT OF THE COMMENTS! If you're teleporting outside of the box... your computer is lagging. Try playing the game on this website: http://phosphorus.github.io/ It should eliminate the lag. Side effect is it may remove the music. Scroll down for the game controls: Control the player with the arrow keys (hold Z to slow down). In RED mode, you can move the player in all directions. In BLUE mode, the player moves like in a platformer. "Might" make this into an actual boss fight someday... "M" to mute out all game sounds.
Thx to original,I'm probably gonna add sans and papyrus sprites to make it look like sans and papyrus are combing gaster blasters too fight you. Other than that it's the same,so yea! Enjoy!Press spaceXD
