The greatest flash port ever created.
This game is incredible and I want more. I really enjoyed powering up in this, your character basically become unstoppable once you obtained a fire flower. Bill and Samus are by far the best characters to use once you get their Fire Flower, which shows that there are still some balancing issues but because it looks like you ripped the characters directly from their respective games it's not all that surprising. You did an excellent job with that.
Link is terrible, though It's almost like playing with a severe handicap (just left a bad taste in my mouth using him). His upward and downward thrust moves are useless for killing enemies because even at tier 3 he takes 2 hits to kill them.
Mario is obviously just plain as hell, but I liked the possibility of playing the original game, because even without the extra characters this is the best SMB flash port I've ever played.
Give us some more, this was insanely well designed, the music all fit perfectly and it has lots of replay potential. I loved it.
