I liked the graphics, it reminded me a bit of "collage". The absurd peanut characters is an artistic choice I can get behind, but the pink cow with a phone using Comic Sans and using modern acronyms was really out of place imho.
The whole game is based on absurd, but even knowing that, I didn't really understand the ending. :(
Sound-based puzzles are uncommon, so it was nice to have one here. :)
