Mmm, well if this game is indeed meant for kids or not is not that relevant I think... The question would more be like, does this blood fit to the game's style? If you'd ask me, I don't think it fits, like others said... Not because I dislike a little (or a lot) violence here or there, but if you want to make this game violent, then it shouldn't be cartoony and sweet the way it is... But maybe this is just too much based on those screenshots, and is it in-game less different in style? Anyways the whole concept is rather original and it looks pretty good,

Cheers
