Click the flag a few times. Use W A S D to walk. Use space to teleport. Use z to interact with things. Press C to sprint. There are now boundaries. Ex: San's sock, the pet rock, etc. PAPYRUS and San's rooms are now accessible by pressing z while at the rooms' doors. E to catch up on ur sleep and Q for dog. I got rid of the shack. ----------------------------TIMELINE------------------------------ This is after the pacifist route, when the monsters and humans are living in peace. Some of the monsters, including Sans and his brother Papyrus, moved back to Snowdin, or simply didn't move out at all.
thanks to @goldchica909 and @stfono5666 for the original projects. I didn't change too much, just improved a couple things and added some new features. It is now finished. Took me long enough. Also, you can do the frisk dance...ish.
