Chapter 2 is available on Itch.io and Newgrounds. I've created a second game, with a bit more rooms, more exhibits to contain, and a bit more complex gameplay.
I hope to create at least one more, with random-generated museums, and then, hopefully I can start working on a "not retro" version of this game.
I'm also planning to add some more elements (inventory, a leveling system), to enhance the gameplay, and add some more mechanics (i.e. Doors, that can be closed, more usable objects) so the night guard has a more complicated job.
