I really like the idea of this puzzle game, it's pretty original. I also like the style you went for and the music. What i think you really should improve is explaining the rules: they are a bit confusing at first. I strongly suggest you putting the rule table in the game screen. maybe under the time left, so I can check it at any time. There are also some typos in the instructions (puzzel, who knows what happened), and sometimes i got hit just by staying still at the bottom, i don't think that should happen.
For a first game, you did an amazing job
