We were a two person team (programmer and artist) and while i was messing with Godot's AnimationPlayers and learning how SubViewports work, my partner was drawing our collectible monsters! She would draw a basic design on a sticky note, hand it to me, and I'd write a name for the monster on it and send it back.
We were originally gonna ask friends and other jam participants to design monsters for us, but nobody responded fast enough so the only outside design that made it in was the artist's boyfriend's design Francis.
