Really cool stuff! I finished it after 2 tries. Really good maps, made only walking and only running both impossible, you had to figure out when to walk and when to run, nice!
Didn't enjoy that my life timer got reset between levels, would've enjoyed it more with a persistent clock. Made my super-awsm map finishes feel nullified.
Tutorial was really impressive but perhaps a little unnecesary, why not build the tutorial into the first few levels and then just teach the player by default as they get started with the game :]
Overall awsm stuff, sad that I didn't get to see the human form nicely at the end though!
