Excellent
This is a very well made game. I think the concept of this game is very good, and I like the rather pixelated graphics; you obviously spent a lot of time working to make this. The difficulty level isn't that good; I mean, the first level is way too easy, the second level is just a tad too hard, but the third level is way too hard. That thing in the middle always makes me lose.
The scripting in this game is also excellent. There are hardly any glitches, and the enemies always go the right way, without getting stuck walking into walls like they do in most PROFESSIONAL video games.
The audio is pretty good, but the music gets repetitive, there's not much to the music, and the mute button has a small glitch in it: if you mute the audio, then turn it back on, the music doesn't play.
I think that even though there is not much violence, the violence level is pretty good. When you defeat one of the enemies they "explode", (or something like that,) and that is very original.
Overall, this is an absolutely fabulous game, but you should make the amount of money that is currently possessed labeled "money" instead of "gold". After all, why would an alien carry gold around? Regular money makes more sense, especially in this day of age.
As I have said before, that I want to emphasize, is that this is a great game. Keep up the good work.
