It took me a few long sessions to clear the game- I guess I don't have much raw video game talent. I was able to get very good with practice/memorization, to the point that I could clear the game on a single life. I really enjoyed the jump/attack mechanics- there's a great rhythm to the game that comes out once you know where the enemies will be, and how to kill each one. I recommend you stick with it, definitely my favorite action platformer to date.
