Loved it.
It's quite amazing to see how far along "Mario vs. Sonic" fights have come all the way back to Randy Solem to such greatness as this one,this had a lot of creativeness to it with all the different scenes they we're fighting against plus the moves we're quite cool and it had a good pace to it all with it not being too slow but not insanely fast either,the length of the fight was also a huge plus cause it seemed to have lasted well over 5 minutes and i like that it had Eggman,Metal Sonic & Bowser in it as well but as for the animated scene i think you could have done without it and just had it sprited as everything else was but when Super Sonic came to the scene the pace picked up really fast with the fights and it was very enjoyable for that time also the couple of Eggman "penis" phrases was quite humorous,overall i enjoyed this Mario vs. Sonic fight very much and this could be possibly the best one i have seen,excellent job man. =)
