AI needs work and the game is too short. But the concept, graphics, and storyline are all entertaining. I also enjoyed the music. Just give the game a little cleaning up and lengthening. 4/5
I think the animation needs to be taken up several notches if this will be the premier game of this website. It doesn't even compare to many other games already present.
Because of the difficulty in getting people onto the server, it might be a wise idea to add computer controlled players as an option. Otherwise, people like myself may never get to try this game.
I love this concept. Mario is a truly great franchise. However, I think you have made some of the platforming elements a bit too difficult. And crouch jumping can be difficult.
