I'm surprised at all the reviewers. Unlike most (apparently), I actually tried out the game system. Let's see what I can give you on THIS one :).
Game Overall -
Okay, you have your character that can jump, shoot, move, and react to the environment even allowing for a special when the yellow bar fills up.
Enemies: Yeah, there was one. However, it's really lacking. I'm surprised with the apparent power that the person has (you having to walk through the "maze" and all [this isn't a joke or sarcasm, by the way]), I feel there should be sub-minions at the least. It annoyed the hell out of me, though, walking up to her and the movie part taking over. I feel the movie that came should've been after an actual fight with her.
Engine: This needs work, too. It looks nice, yes, but it's lacking some of the most important parts, which is the enemy to pc reactions. Hypothetically, if I get shot by Minion A I should lose 3% health. If I shoot said Minion, he should lose... say, 20% health. What tells the game itself that my shots (and his as well) are hitting? What tells the game that I'm in Minion A's firing range? What tells the game where my shots should end at? If I hit the minion, it should stop at him, right? Or even the wall for that matter.
Interface: A cleaner interface would be nice. The Controls should be in the Controls option from the main menu, IMHO. Just try to clean it up a bit and only put important information there.
Special Attack: I liked this concept, but there needs to be more behind it. Is this the only special attack I'm allowed? Will I be able to change it? Does it change mission by mission? Will there be another button for me to press to initiate a different move? Perhaps SHIFT + S for the special "Surging Plasma" would be sufficent, and work well for whenever the PC has more specials allowed to them.
Misc.: The background needs more work and detail to it. The character has a very Samus Aran/Metroid type stance (I like it, personally :)). The movie portion lacks plot. My biggest complaint, though, was the sudden stop of Voice acting. There's no reason you couldn't have implemented it during the battle as well. The music is there to heighten the user's mood to your set the mood, not create it :). Good job on your submission and I'll follow up and see what you can come up with. Hope this helps.
