Robot in the Dusty Archives

In the future even robots can be curious and there just might be some lost knowledge deep in the dusty archives.

I've been a big reader since I was a child and while my apartment is a bit less dusty, the general state of book related things is closer to this image than it probably should. I will collapse the floor sooner or later.

I drew this for a personal game I'm working on and this will go into a small puzzle minigame where you have to find hidden images. Not telling exactly what will be hidden in what way, but there is a fairly obvious hint in this illustration. And here's the game so far. Give it a try, it's completely free: https://ultra-shenanigans.itch.io/human-upgrade-labs
