I really like the idea of a stealth streaking strategy game, especially the twist with the selfie levels (that was a really clever way to motivate having to visit multiple spots in a level), but most of the levels ended up feeling pretty samey to me. Like, for the most part, I just plowed ahead until someone was in my way, diddled around until they moved (because there was always a safe spot right there to do so), and then repeated until I was at the goal.
I think if I were making this game, I'd have tried adding things that you can actively manipulate or use, because you can only passively move and wait around and I think that might limit the kinds of "unique situations" you can get into. A couple of ideas off the top of my head: a way to temporarily distract NPCs by having them pause or turn in a direction they normally wouldn't, and movable cover you can push/pull to block sight lines (I think this could open up some really interesting possibilities if the moving NPCs could also push them around, but then that would add some real complexities to both level design and even just the game logic).
Cool base here for sure though!
