In this challenge, the Player cannot walk, however, they will have the Grappling Hook at the very start and can use it infinitely, as it always reappears in the first inventory slot. The Player therefore has 4 empty slots to store other items.
Mrs. Pomp will give the Player 2 minutes to meet her in her class. It's a Bully will not take the Grappling Hook from the inventory.
If the Grappling Hook is spammed by the Player, sometimes the Grappling Hook will float in the air.
It is possible to prevent Baldi and the other characters from ever spawning, by using the Grappling Hook on the blue locker near the starting elevator and spamming the interact key. Doing so will prevent the elevator from ever closing and Baldi from ever spawning, allowing the Player to freely beat the game. The only way to fix the bug is restarting or winning. mystman12 has yet to fix this core issue, and the blue locker near the start of the challenge has been removed and replaced with the red one instead in V1.1.
A window from one of the walls has a blank (white) texture known to be the window mask. This was fixed in the V1.1 update.
Prior to V1.1, the Player can get stuck in doors and elevator shutters if they shut while being pulled towards them by using the Grappling Hook.
Before V1.1, It's a Bully will sometimes not disappear even when the Player has other items, not only the Grappling Hook.
↑"My current plan is to unlock challenge maps as you discover stuff in the main game. So for example, you wouldn't unlock the grappling hook challenge map until you find the grappling hook in the main game. I'll probably end up making some challenges unlock by other means, like reaching a certain point in the main game or beating other challenge maps. So while some challenges may be locked behind beating the game, most will not." - Baldi's Basics Plus Steam Community Hub
