Unfortunately I didn't play this one during the Jam so I can't quite make a comparison, I did find the tutorial while walking you through the basics of doesn't do a great job of explaining the actual controls, perhaps on level one you could make it two moves (introduce the shifting keys right away) and then level 2 introduces the up down shifts. I would also explain on level 3 using walls to shift. These first couple levels aren't so much puzzles but education of the mechanics.
I love the SFX, really felt the movement with that.
I think this was mostly on me but there was a couple of instances of "running into to walls" to move keys and I lost track of which direction I was going, that got frustrating fast.
Awesome concept and really nice implementation.
