So, I'm not exactly sure what's going on, but this seems to be a fairly standard platformer. The art and presentation is pretty good and has potential, I can see you really going somewhere with this. You even kept a pixel consistency which many people seem to not do. Props for that!
I found that whenever I fell into a hole, there seems to be no sort of death condition. So I end up having to Alt+F4 to restart the game. Also, the main gimmick seems to be nowhere to be found. These may be bugs and will probably be fixed in the future.
Again, good job with the art! I think the gameplay needs a bit more work though.
