the color palette, the explosions, the huts.... those are the things that make it look cartoony, imo.
I think that is where the DE comments were coming from as well.
I also agree about the characters bordering on caricatures, which falls in the cartoon realm.
Someone earlier talked about the playfield looking retro... but retro games don't have realistic skinned bodies and spines and skulls.... so there is some split personality going on.
If I were to offer my humble opinion, that would be to push the art more into the realistic world, make this game look like an R-rated pin, just as the movie is r-rated. Won't be for everyone, but they aren't trying to sell it to everyone, and that bridge has been crossed with the toys.
