A standard project of M.U.G.E.N. combined with Super Smash Bros elements. A crossover parody that unites franchises such as Super Mario Bros., Zelda, Sonic the Hedgehog, Pac-Man, Wreck-It Ralph, Street Fighter and Q*Bert.
Although as a rule it's a game more made with M.U.G.E.N., I think it's a good project. It has a decent selection of characters, and it's quite sensational to face such powerful rivals as Ryu and Bowser, and even Q*Bert and Mario in some cases. Good game despite a few bugs (but it's solved with cheats).
Good fighting game, yes.
