Success!

What a wonderfully unique idea for a puzzle game, great work!

Really well made game. But please put hints for new players.

Fun game until I hit level 4. I'm not sure what the trick is to solving this level. I did manage after about 25 restarts to get into the little room and back out, but darned if I know what I did! And I still couldn't solve it! I thought I could be slick and borrow a box from the previous level, but no such luck. Ha! :)

This is the most intuitive puzzle game you've made yet, but it's still very confusing to start out with. The core concept is much simpler than the previous games.

If the different objects were numbered according to their height, or at least looked different at a glance, that would help a lot.

The introductory levels should do a better job of making the player understand how swapping works. They feel too easy to breeze through by just pressing space without ever grasping the concept. This is the main reason the level where the shortest block is walled in is so difficult to players, besides looking more complicated than it is thanks to the layout.
