Bravo!
Very well done my friend! I watched and enjoyed your first one (came out the same day as an episode in my sprite series MMX OLB:-p) the second installment was actually even more enjoyable. Your use with sprites is very clean and smooth, and you staged the fights very nicely. Also think you make a nice parallel between Sonic and Megaman. And I loved the char select part, very nice touch. The only thing I think you could really improve would be the script a little. The dialogue just.. didn’t seem natural. But that’s not too important, you made up for that through your animation.
Quick question, where did you get your sound effects from?
All in all great job and I look forward to the next one!
