There seems to be an online aesthetic of crude stick figures and line drawings, at least in my regular visits – typical would be the strip xkcd or the RPG Kingdom of Loathing. While the sketches here are significantly more artistic, the Myst-style game daymare town has a similar feel – minimalist sketches of a seemingly deserted world scattered with puzzles and items to collect [via not martha]. I haven’t played my way through the whole game (there doesn’t seem to be a save option and I unfortunately closed my browser window before finishing it) but I’m definitely going to go back to it. The creator, Mateusz Skutnik seems to have a few other games as well as some comics linked through their site that I want to look at sometime soon.
