It would be possible for sure, provided you have a good enough model to create a given kind of images. Although no, there is actually no "source" and "derived" images.
I've been working on this mouse over feature for a month now, and by "working" I mean remembering every now and then that I have to add it, it's just one line of code, so I'll do it next time I open the engine. And then forgeting about it next time I open the engine. I actually implemented it after reading this comment though!
You're right here, I was concerned about mechanical identities but kinda forgot to add the simplest baseline damaging cards, in the process. The effect is that emojis I pinned down as "having healing" have too much of it. Notifications, highlights etc. I'm already working on!
Dope idea for a puzzle game imo. If you had a pre-defined set of guns to use on every level (not buying) + ability to revert the placements with no cost, or at least see the change in route before placing them, you could get a cool pure puzzle game from the rerouting mechanic alone.
Thanks for feedback! Tbh I actually thought of keeping Kevin MacLeod (with more tracks though) as a soundtrack because of his status as the meme music source on youtube.
