You know what game is just totally the Bee's Knees?
VECTOR MAN MOTHER FUCKER!
http://en.wikipedia.org/wiki/Vectorman
Vector Man for the sega genesis is the fucking ultimate.
I was going through the sega library (how you ask? well, I plead the 5th

)
since I really have never played any genesis games and I just picked one that sounded cool... and SHABAMM! VECTOR MAN!
It's a side scroller shooter... and a really fucking good one.
HINTS:
-If you shoot down when you are falling you can slow your decent to a controlled fall.
-Shoot all the televisions!
-When walking up an incline press down and shoot and you will aim up the incline perfectly parallel to it.
PLAY IT!
it's on steam if you feel like being a good person and buying it
