This is amazing. It took me some time to understand the idea, but once you get it - this is so cool. The potential here is huge. I don't think each level must end with a platform to jump on - any of interesting obstacles in the middle of the level could be a final one as well. Ability to walk in any of 4 directions might give too much freedom as you can walk anywhere backwards, not obligated to use "joined" feature. Most struggles with understanding the game for me was because of animation - "idle" mode is so wobbly and appears as active as pushing animation, so I didn't even notice push action at first. Overall pace and animation could be tweaked to highlight actions of the character - as it's very important what he does and in what order. Still awesome atmosphere, both sound and visuals, enjoyed playing this!
