Lovely smooth platforming in this, such a well-polished game, doesn't feel like a jam game at all! :)
I really liked finding the secret areas, it was fun looking out for the slight differences in textures. The sliding block puzzles were really cool too, a very nice addition to the run 'n' gun formula.
Just to add to what I said on the game page, really good use of the tileset; it's easy for ToyBoxJam games to end up looking like they've been pieced together, definitely not the case here :D
