Nice game! You worked well with the mechanic. The character moves a little slow but the levels were designed well. Very good for a first jam!

Coll game. I really missed the mechanic of falling in this platformer :)

Although the walking speed could be a bit faster.

Very solid game. Good invisible tutorials, the second fan level is my only peeve about this game. For a simple a game I was addicted and played the whole thing even when I got frustrated. Good game and good luck. 

Hope you have the chance to go check out my game and rate it. Thank you :)

Ditto about the tutorial, very nice. Not sure about the not being able to switch in mid air though. 

Neat concept and some really clever puzzles. I liked the part where you teach the mechanic by having the player walk out over the spikes, that was a very memorable tutorial.

I think this is a really amazing game just ignoring the slight jankiness. With a bit more polish, you can easily make an amazing puzzle game with this as a frame work. One thing I'd recommend is letting the player push as well as pull the boxes, it really sucks when I have to restart an entire level because I accidentally nudged a box too far for me to fix.
