Samus Aran would be proud.
If you are looking for criticism then don't read this post. I have nothing bad to say about this game. Reminds me so much of the best metroid "Super Metroid."
The controls were simply flawless, the wall jump was effortless smooth and fast. Plus the ability to grab ledges? In a flash game? I don't remember the last flash game I have played with that. Everything in this game screams #1, and I look forward to playing through it extensively. You sir have earned yourself many fans with this one. Well done.
