Not Bad.
Everything about this game is above average, but there are things that could definitely be improved upon (hence, the 7s):
-The engine. Pretty cool, especially given the level editing capabilities. The scrolling is nifty too, though it's annoying when the character falls faster than the camera follows and she ends up off the screen until the camera catches up. Also: the controls feel very sluggish. I have a new computer with 2 GB of RAM and a Core 2 Duo processor. Starcraft FA 5 runs at 93% on my rig. So it ain't because I need to set it at low quality--there's something up with the code itself.
-The graphics. Good, particularly in terms of the environmental detail, but as others have pointed out, the main character moves stiffly and looks quite unnatural.
-The sound. The sound effects are serviceable, but not much beyond that. The main theme music is very good; I wasn't too crazy about the music in the Temple of Bast, though. It was a little too "in your face" without actually energizing me.
-The combat. Annoying. The default weapon is awful, and you can't really do much running and dodging because you just end up rolling straight into traps.
-The puzzles. Very simplistic. Not even as complex as the "find the key card for this door" puzzles in old shooter games.
There are many areas here where there is room for improvement, but on the whole you've done a good job with this release. Keep working on it! :-)
