Don't know if it's a bug or I'm just bad at playing, but on mobile (Android user) I can't actually get into the office or the cafeteria to complete the game. I've tried to see if it had to do with my items, the broom, or if I could slide past the barrier and into the office while a roach was having it's way, none of which worked but that last one got me glitched out of the map and half a titan roach Sprite was seen in the void.
This is the office door, you can also join my discord to see a quick playthrough of the game https://discord.gg/MJxq6zyrRh
