It's a very simple game, but it is a nice little experience, I hesitate to say this fully fits in the metroidvania category over just the platformer category, though. However as another comment said you do have some of the general principles of one included. The controls could've used a bit more work. The double-jump loses height way too fast as you ascend from your first jump, and the edges of terrain have this weird little hook. Other than that, it's a neat little game, bare-bones if anything.
