This game was really fun. I got to a score of 50!
A suggestion I have would be to take into account how well you do in each minigame into the scoring somehow. This would encourage you to perform better, especially early on when the game is pretty easy. Also, try to use as few buttons as possible so the player doesn't have to move their hands between minigames. I'm particularly referring to the Freddy minigame which uses the F key when none of the other games do. Finally, try to even out the difficulty more. The Chica and Foxy games were really easy while the Freddy and Bonnie ones were a lot harder.
It's less so 4 games in one, but more akin to WarioWare or Dumb Ways to Die where it's a sequence of microgames, which is a great idea. You had a limited amount of time with this Jam of course, but in the future, adding more minigames with different FNAF games and characters would give it much more variety. Great work!
