I'd echo what the others have said about the tutorial being pretty long, although it had a bunch of humor to it and was actually pretty entertaining to go through.
The puzzles were at a great difficulty level. My issue with it is how in puzzle games, the difficulty should stem almost entirely from complex puzzles and having to come up with a solution. Once you realize what the solution is, it shouldn't be tedious to implement that solution. In some of the levels, that was kind of the case, because it required some specific platforming or landing in the right spot on spikes.
Here's a great reference on this topic.

Regardless, this is still one of the best games I've played this jam. Lots of impressive work from everyone involved, especially in this short of a time limit!
