It's Okay
Graphics: Though they were ripped, there were problems. Mario never stopped walking, the sprites were stretched to different sizes... It just didn't really seem to fit together.
Style: It was fairly frustrating because you keep falling through the blocks, you don't need to jump on the switch to switch it, etc. A higher FPS rate would do WONDERS for this game; it seemed quite jerky.
Sound: The music went well with the game, but there weren't enough sound effects.
Violence: There doesn't really need to be much violence in a Mario game, considering it's mainly family-oriented, but you should AT LEAST make something happen, such as a noise, or turning red, when you get hit by the saw blade. The only indication that you were hit was your HP bar, which you have to look away from your character to see in most cases.
Interactivity: You should be able to do more things, like grow/shrink, or at least duck. Just walking and jumping didn't really cut it.
Humor: It doesn't have to be funny, but it just wasn't that interesting to play. Nevertheless, I played 3 times to try to beat it. It made me angry to have to start over from the very beginning if I died once, though.
Overall: Average. It wasn't a BAD game, but it could have been a lot better.
