Hourglass Temple

They say that in a faraway land, there's a place where time runs both ways.

Controls:

WASD or arrow keys: Move around
X or C or Space or Enter: Context-sensitive action. Pick up and put down boxes, drop orange boxes, and un-drop pink boxes.
Z or U : Undo
R : Restart the level
M : Mute
Esc : Exit to level select

Notes:

You can climb steps one square high by walking into them. Falling two squares is safe, even if you're carrying something, but falling three will hurt.

Orange boxes are normal, but pink ones are going backwards in time. If you drop a box off a ledge, then in reverse it looks like it's flying up into your hands. That's strange to us, but perfectly normal to the pink boxes! But it also means you can't drop pink boxes hard, only put them down gently: from their perspective, it wouldn't make sense for you to drop them.
