Mega Mo (2005)

I was a really big fan of Matt Thorson's game Jumper (mattmakesgames.com) when I was younger, and I tried and failed many times to make my own huge epic Jumper fangame. But I did manage to finish this weird little one-level Jumper/Megaman crossover. 

It's difficult and kind of annoying but very short. You get ranked on your time and number of deaths at the end. I don't think anything interesting happens if you get the highest rank.

Z to jump, X to shoot. You have a charge shot.
