This is cool! I your descriptions -- you've included some details about behaviour that I left out of the in-game ones. That being said, I don't think the ice goblin actually exists. You're giving me ideas though.
If you'd like enemy stats, short descriptions & more accurate names, try throwing a certain orb at enemies....
Side note, I've long been mulling over making a sort of deluxe version of this game, and one of the features I'd like to add is a bestiary / item compendium that unlocks across runs as you identify things.
