Art Treachery is my entry to the British Library Labs Crowdsourcing Game Jam In this game you are an art thief, sneaking into a museum with a very specific mission. Instructions on how to play can be found ingame. The game is unfinished but playable.
You could try to play Art Treachery in your browser but it will probably run slowly or not at all (depending on your browser). So I recommend you download it.
More info and download on Art Treachery on itch.io
