The lvl 1 and 2 doors have a chance to be Barricaded and sometimes a crowbar doesn't spawn anywhere near to pry them off so to fix this it should be IMPOSSIBLE for those doors to be barricaded.
If you open the lvl 3 door on the roof (map 5 once again) when you enter you can come across a bricked off floor/ceiling which makes that use of the keycard an absolute waste. Speaking of that door, why does it exist?
There are 2 BIG skips the kids can do to get access to places without a Key card.
Doing some parkour with a sauce bottle can get you over the Lvl 2 Door. Just. a. sauce bottle (i'm not going to explain it so no one else can do it just put a roof over the lvl 2 door so it blocks it and works as a bridge when on top)
Behind the circus if you jump on the poll you can eventually get on the planks and access the lvl 4 area without anything. Literally nothing
