Because as a woman....
The only thing i can do to entertain myself is buy a bunch of crap i don't need. When i was a little girl i would have chosen Commander Keen over this gender-stereotyped nonsense any day.
The idea is too old. It was fun for a really short while. But I've seen many games like this on other sites... etc.
I'll give this a 6 / 10 , 3/5
