I'm glad you're enjoying it!
I would like to do something like that, but spritework is my weakness and I find it hard to make new player animations, so maybe some day but no promises unfortunately.
It'd just be nice to have some way to speed it up! An animation isn't 100% necessary- that's something that slows progress for Project G.L.U.T.T., too. (And something I desperately tried to avoid with how I've rigged up my systems.)
It's just that without a way to speed it up, you're stuck with the base idle-digestion speed- and this can take a lot of waiting to empty out!
