I think you've done a great job, it looks good and the character works well - but they definitely need some tweaking. The dust animations and running about looked and felt good except I found the wall running almost unnecessary to the level design, most areas you could just kick about to get where you needed and the wall running ended up being more of a nuisance when travelling around. The art style was good and being able to explore different sides of the level worked, but with the camera being a bit difficult at times it made it hard to figure out where to go. Overall I enjoyed it, good stuff :)
