Pure awesome! I understand that this is a still in development demo, but damn is it good so far! There were a few platforms I couldn't reach and I have a feeling there's a double jump upgrade hidden in there somewhere, I just never found it. The art style is awesome, the music is fantastic, the sound design is heavy and impactful and the gameplay is spot on! The only two things I wish were in here were some kind of dodge, since heath can be a little scare and enemies like to bunch up on you, and the ability to check the effects of the items you have. Other than that, this is just so damn good!
