I like the movement. But seems a bit slow as far as getting from point A to point B. I found my self jumping and dashing to get there faster. The footsteps sounds seem a bit to repetitive. Maybe add some more pitch variation in each step. You really need a edge grab. Getting stuck on a edge and then falling kills the flow of the game. You nailed the animations. Reminds me of Banjo Kazooie.
I also am trying to make a game and I understand what it takes to make stuff work. Your doing a great job so far. Your progress is way better then mine. I was just letting you know what I noticed when playing the demo from a fresh set of eyes. Don't take anything as criticism. Keep up the great work.
