You have had some problems with the deadline and uploading your game also.
I played your game anyway. The art is good and the animation of the character also. The music is a bit repetitive, but I know how hard it is to create a good one. I personally think that the levels are a bit boring, but that's easy to fix.
I also find some bugs:
- I was able to jump tremendously high if I pressed W, Arrow Up and Space at the same time
- In the 3rd level (red blocks) the stairs were very slippery. Also the blocks were not ordererd correctly, because I was able to look through horizontally and see the background.
But for that time we had, it is a good game.
