Take Note that Jeff's Shop has a chance to Open and Close Once its Close you can't buy any items from his shop. Only when the Shop is open. And take note yet again this is automatic and this type of feature only works when you place the jeff table, jeff,gate together.

if your lazy to build use a structure block and type mystructure:door52

                                                                                                                                                                                                                                                                                               Take Note to make glitch to teleport you right you need to spawn the Glitch teleport mark that looks like that photo in the bottom. so basically you can spawn it anywhere so Glitch can teleport you but spawning too many teleport marks will make glitch teleport sequence not happen.

 Take Note to make your maps more realistic spawn the light furniture it will detect monsters coming like rush. but however, once rush or ambush passes by, the light furniture will break just like in the original game.

 this is not a note to be honest...

A60 v1- /summon doors:a_60v1

A60 v2- /summon doors:a_602

 Take Note getting in the closet 5 times will cause jack to spawn. This behaviour works the same with the metal wardrobe as well but its decoy who will spawn in that one.

oh yeah don't forget to not take long inside the closet because an entity will appear to force you to get out.
