I really like the art design. You did the retro style well but the black-and-white twist is very neat; I've not seen that done before.
Sound design is pretty good, no painfully loud SFX, no weirdly quiet interactions. Nice music/ambience, nice interaction sounds. The conveyor belt sounds very nice too.
Controls were a bit confusing at first but I got the gist of it. It was fun making little abominations, lol.
Short but sweet. Good submission.
