Not bad at all
Pretty good for your first game. I know how hard it is to make a working game...I can't do actionscript to save my life, lol, so you did a damn good job. No glitches that I noticed.
Review score breakdown:
Graphics: 7. Simple, but sufficient. The graphics weren't jerky, the animation was smooth...pretty good.
Style: 8. Despite being a relatively simple game, it was still fun to play. The multiple weapons and overheat meter were a nice touch. The hit detection was very accurate as well. Very nice.
Sound: 0. Add some sound, man! :-P
Violence: 5. Explosions and such. No blood or gore or whatnot. I don't really know why violence is a review category, not like it's always a good/bad thing, lol. But yes, in this case, lasers and missiles and explosions were a win.
Interactivity: 8. Multiple weapons, overheat meter for the lasers, and the fact that this is a fully functional game make you get high marks in this category.
Humor: 0. It's a shooter game, no room for humor here, lol.
Overall: 8. Very nice for your first game. No noticeable glitches, good hit detection, modest graphics...congratulations on a great first try. :-D
Ways to improve: SOUND, lol. That's the only thing this lacks. A good shooter needs awesome SFX/background music as much as it needs weapons, heh.
I hope to see more from you in the future, and I'm sure you'll improve as you keep practicing. Your good try earns a fifen from me, good sir. ^_^
