Ok, more things to fix.
1. When Samus was running across the bridge, she looked like she was split in half. I guess it was the program you used.
2. Another thing. When you use one sprite, don't switch halfway through. The Samus sprite you used was from Super Metroid, then you suddenly switched to a scratch or edit Samus. It was clearly visable. The same goes for Luigi.
3. 3-D=Scary in 2-D things. Remember that well.
Hope I havent forgotten anything..
Nice ending with Luigi. That was funny. Same with Samus running across the bridge and the sign thing.
Remember: Don't mix sprites around midway through the movie, and DON'T ever mix bittages. (Like 8-bit with 32-bit, ect.)
