Original game.
Never seen anything like it among all the Mario games. It's very original and puzzling but at the same time fun, with the sick new upgrades and all. Also, I haven't gotten very far in the game yet but the part with the star jumping is well thought out. Another thing though, that bothers me, is how slow the plumber guy moves. Is it just me or does it take forever for him to get from one side to the other?
Maybe it's just me.
Overall, great job! Wouldn't have expected these things from this kinda game.
