The Switcher Post-Jam Update

That level where the portal box falls on the spikes and then covers up all of them was pretty neat. No idea how you did that.

From a platforming standpoint, I feel like the character moves a bit too slow and there's a few other things, like how you can't jump when you're on the edge of a diagonal wood platform. There's this video I like to refer people to (bit of an inflammatory title, but it's certainly helped me out with platformer mechanics): 

The platform boxes also have hard corners, which makes it a bit annoying to get into. You could maybe make them ramp very slightly inward so you can smoothly walk into them, or so you can easily push smaller boxes into the large portal box.
