1.3.3:
Music soundtrack in version
Buttons were more sharp and not as round in
Mobile phones vibrate when baldi slaps his ruler
The achievement icon for 3 am was the Weird 99 eyes
You didn't have to click the top right button to activate the mod menu, you needed to be afk for 15 minutes while touching the screen (android)
The title page was different
Version 2:
Typing SO SO SO many numbers in the math notebook can cause BadSum screen saying that the number was not a number because it was too big to be calculated
By using mod menu, if you make your speed at least 9000 and walk with it for a few seconds, you'll see your good ol' friend, BadSum! And he's here to say that you were too fast which broke the game
1.8 (old and not version 2 beta)
It said "!-EVILVERSE IS LANDING, TAKE COVER-!"
everything was hued in red (maybe as April fools joke?)
The good ending where all the notebooks are wrong (mod menu can be used to get this) as just like the normal one, but with green text and playtime music from baldi's basics plus
