My first attempt I died to the seemingly impossible fairy and what looked like Cthulhu vampire. My second attempt I went to the left and was alone with the fairy and unleashed every skill as much as I could until it was dead. Then there were no more enemies, and I couldn't progress through the level. Third attempt, I was writing this comment, and went back half way through to be at less than half health. So I ran all the way to the right again and everybody stopped attacking me, so I could easily kill them with the lasers and lightning bolt skills. I'm not sure if I killed the octopus arms or if they just disappeared.
It's a great looking game! I agree with CFHM, that sounds & Music would go a long way! Allowing the player to spam every action is kinda fun, but takes any challenge out of the game.
