Awesome! the game is fluid, the art is perfect and it is easy to pick up. I WAAAAAANT a full release, actually I need it.
Also I have some feedback with bugs and all :
When you die the time doesnt reset, a proper tutorial could be usefull, at first I was avoiding the enemy instead of jumping on theim. maybe the WASD could be added and thats kind of it.
Now the positive feedback that I've found unique about your game. The box picking "puzle" were fun, the character is easy to control, the black background is splendid and the score is a good impliment.
