The tutorials were spot on, and I like that you can view them anytime you want.
The environment gradually burning around is also pretty damn cool.
This is just a nitpick of mine but I think the music can be improved just a bit, it feels a tad bit shallow for the situation and because of that it get's repetitive.
I think the reason buckshot doesn't have this is because the music has more depth and it feels close to the games animation style and speed. Again, this is just my opinion but I really can't think of anything else that would improve this game since it's already pretty darn polished on all the other things.
I'll be wating for the full release, really enjoyed this demo.
