The first picture is an old version of floor 1.5, but it's scrapped as it's just a copy of one of the rooms from TRTF 5 Revival.

The second picture is a lock for the first floor, but its design.... Strange. What kind of arab fani was going on in my head I do not know myself, do not ask!

The third picture is different from the others in that it has a chance to get into the game, but most likely I will change it.
