To get the update, redownload the game.
Patch Log:

- Foxy's movement AI no longer remains the same trough playing further levels if you've got him out of the cove once. This resulted Foxy attacking at the beggining of the night even on full music box, which will hopefully no longer be the case

- Removed the debug key that could unlock all nights in the main menu

- Night 4 no longer gives the night 5 ending

- Fixed the typo in Shadow Foxy's description

- Replaying the night from the Game Over menu skips the intro of the loading frame correctly now

The glitch with the Tic Tac Toe still remains. I need to take a closer look at it.

No progress on optimization has been done yet because the issue seems more complex than I thought. I tried a few things all of which have failed. It will be the focus of a further Pre Release.

Also a tip from me - cameras are useless and you only need to wind up Foxy's music box on them. Check the door lights regularly and when Chica's at the doors, turn the fan off UNTIL she leaves, then you can turn it back on. The controlled shock works only on Bonnie. Don't spam E on Golden Mangle, hold it.

Also remember when in doubt about a mechanic, read the almanac in the main menu.

Still taking feedback and bug report. Ideas and changes to features are welcome too.
