I love the idea so much, and the creatures you can make are just weird and wonderful. The pixelwork for the parts is very good. (Is there a way to remove parts from your creature, or are you always just adding on?) Overall, an enjoyable game.
There isn't a way to remove parts per se, but some parts can overwrite others. For example, legs can go on top of torso segments. I was going to have a more complex monster-builder, but I ran out of time.
