Metroid Quest: In the Making

I am in the process of making a Metroid game for 2.5. It will have Custom Enemies, Bosses, Scripts, and a bunch of other stuff. I have 4 videos (more to come) of the game, and I would like to know what you guys think.

Story: This takes place after Super Metroid and Before whatever comes next. (I think it's Fusion or something). There was a bounty for anyone that could destroy a Space Pirate Frigate. As Samus goes there, she is attacked by Ridley and her ship is damaged. She then is forced to take salvation on a nearby planet and needs to do repair her ship but she discovers the planet she landed on has many secrets to unfold.

I imported a bunch of metroid sounds, so it fits with the game. I'm kind of at a creative stump, because I can't think of anything to put in the game, but I'm proceeding slowly but surely. I just wanted to know what you guys thought., and If I should make up a demo.

Good start. I espically liked the Lazer Puzzle.

The difficulty looks challenging, but I enjoy a good challenge. The tiles and sprites you use are very well-made, and your opening proudly demonstrates this. I hope you continue work on it, for I would enjoy playing it.
