is this game just a platformer? yes, yes it is. Does it excel at every aspect of it's design, audio, and artwork? Yes yes it does.
The lack of mid air control makes it difficult, but rewarding. I'd be interested to see how it played with more traditional pixel platformer controls.
Music is banger. Art is banging too. I would love to see a 100% full game of this with some of the levels more fine tuned for those of us less skilled.
