Usual step "sequencer" with little to nothing added. Good effort but concept has been abused to death and you should try to add something that makes it worthier.
Not much of an improvement over the concept, jumping is a bit delayed from the actual key-press. (It wouldn't be too much a problem if the game didn't require a certain precision).
Congratulations Jonathon. Really love the game - the "biggest" flaw it has, probably because of the type of sandbox game, is that it is kind of endless. With its lack of restrictions, it provides lots of ways to finish every level: use few tiles, use as much as you can, use only certain kinds of tiles...quite a lot of options. 5/5.
