This is the best submission I have played so far. Awesome visuals btw. The first run was not so great for me, but when I discovered all the possibilities during the second run WOW * - *.
Maybe it helps the player when you kill him in the Beginning at least once ;).
Amazing game, you should keep working on this.
One more thing: Maybe you could add a animation and a sound to the enemys that get hit, just to give the player some feedback on if he hit the enemy or not :D.
