This was an ingenious use of the theme. I really love the entire mimic mechanic. I was surprised at how endearing the googly eyes made everything, too.
My only complaint is that it was pretty easy. I would have expected there to be some kind of "penalty" to transforming back into a mimic, like a short interval where you can't copy anything and are vulnerable. But hey, it's a jam game! It's going to have rough edges.
Great job on this.
