Great game. I love the art style for the game, and it fits the overall feel of the game very well. There has also clearly been a lot of work put into the mechanics, and after my dumbass self got told that you use the arrow keys to move and not wasd I found that the movement was nice and snappy. The level design was good, and although I felt as if it could have used more, you did say that your schedule was rough.
The controls were a little hard to get the hang of, but after I got the feel for them I felt like I had a lot of control, which is good for a puzzle/platformer like this.
Overall, it is a very good game and I feel like if it was worked on more then it could make a good actual release.
