I'll give you a half a star for effort as the controls kind of work though they feel stiff. But, honestly, at this point, it just isn't actually a game because it's unfinished. I'm not trying to be harsh, but I don't think that this is something that was ready to be published because of this reason.
I realize that you know that the enemy can't fight back and that you might have some graphical issues but, those are both big issues almost like "Big Rigs: Over the Road Racing" faced.
A lack of variety of choices of characters and locations with no music and only a bare few sound effects I don't think helps it either. I'm not trying to dash your hopes but, I would work on things like this on your own and consult with friends and have them play test it and try and work on it until its complete before publishing it.
