Contra, havent' heard that name in ages!
Well, I have to tell you the truth: I FUCKING HATE STICK FIGURES... but this brought back some memories.
Me and my cousin used to play 2 player contra for hours (and we never understood the big wall with guns). Yeah, you did make some funny jokes (if you've played contra before). I was never able to hit those flying platforms, lol. And I never knew what was up with that wall (untill I read the instructions booklet, lol).
Good job.
