Yuck
The actual game-play of this game is yuck. I mean the sounds and violence are just stupid (no offence) and bowling balls...what does that have to do with killing wizzards and knights. One way you can avoid the bowling balls is by constant jumping. I did that and it got me through a few levels but all in all i think that you should remove this from NG.
Also if you found the jumping hint helpful tell me. It will take a while to be able to do it.
