This puzzle is a design I made after solving 5L Box and ResQ. I felt the moving door cube was an interesting idea that when added to the square hole vanishing/appearing gave opportunities for an elegant internal solution, like a simple packing puzzle Daedalus.
It has more moves and dexterity than 5L, and some fun traps that can make you think you bricked the whole thing if you do it out of order. (They are just traps, you won’t brick it.)
2LIT = 2/S piece, 2Ls, one Bicube, and one T piece.
