I love the Angry sun. Have you ever killed him with a shell?
I've beat the game, but still love playing it over a lot.
Even though GBA version is cool with tons of extra it also sucks because they modified the levels to make them easier.
I was never very good at contra, but I loved it anyway. Did you know they're actually making a 2d sequel to Super C on the GBDS. It's based off of that game with hand drawn sprites and everything.
