Woah! Awesome looking art this time around! My favorite floaters are 10 and 11, and number 6 is interesting as well. Is that one supposed to look like a plant but can float off at any time? That would be really cool.
As for the worms, I like the ideas for 3, 4, and 11. 11 seems interesting because it could possibly be part of a dungeon or cave system, but would come out of the ground and attack.
As usual, I've added these to the devlog folder
