I love how you make people go to your site to view screenshots and download
Anyways, I wouldn't say this is complete at all.
It lags like hell. (For me at least).
The falling sprite is all wrong.
There is barley any sounds other than the block breaking and coin box and jumping.
There is no music.
There are no animations really except for characters.
The resolution is huge for some reason...
I jump on a Koopa and his shell kills me while it's floating in the air.
I touch a Goomba and die, even though I'm big Mario.
I jump on a Goomba and he doesn't even die, I just fly up into the air.
There's no ducking.
There's no running.
I would never call this a finished Mario engine, let alone a game.
Seriously, this thing needs so much work, it's not even funny.
