Simulation Theory is a game by NimbleBeasts for Github's GameOff 2021 Game Jam. Our interpretation of the theme 'bug' is that the level is not completely cleared due to a bug and you meet your old records again in the form of ghosts.

Wow, this game so perfectly matched the in-game and itch io bg :D


Great game!  The controls are really nice.  Well done with the puzzle aspect of the clones.  I enjoyed playing.


Amazing game. The cloning aspect to complete the levels was very unique and I liked it. Keep up the great work! 


Cool buggy game. It was tricky getting all the right clones to work. I love the art and music


well sucked

Careful with all the bugs! 


i have escaped the simulation. you can glitch yourself through doors with 2 clones. so i guess the trick to escaping was a bug after all.


I managed to shove myself into the locked room with the final ram in it. Nothing can stop me from going into strange portals.


My clone do be bailing me

Haha. You can also use one jumping clone instead of building a staircase 🤣


it's a pretty  fun game with a good music and design !


if you click out of the screen it wont let you click back in , need to fully reload it

For the best experience you will need to download it.


Good :):))::):):)
