This is amazing, hats off to you Sanspirate, I don't even think this is Baldi's Basics anymore. Everything is extremely well made, the only thing I don't really like is the self inserts sprinkled in the mod, none of the tube people are in your style and all look way off from what the game looks like, otherwise, this is a great mod.

Where's The Enterance?

It's replaced with the elevator.
