An honorable showcase of fidelity and smoothness to be expected from a proven veteran of GWJ.
A nitpick I have is that the picker interface, in my opinion, works best when the bugs are in very separate places. A good example of this use-case is Goodbye Deponia, in a section that has you control 3 clones operating in separate environments.
I'm curious of the resources you have used and what you did yourself.
