I'm glad you took a little bit time extra to deliver this complete and quite polished experience.
Sure the tutorial could have been incorporated more smoothly, but this is a level of polish I simply don't expect from a gamejam, especially not one that is this tight on the dev-time. On the contrary I'm glad you made the effort to implement a tutorial.
I really like your art style, but I wished the teleporters would have been better distinguishable.
Overall I think you delivered a nice and clever game.
