Great game and ambience. Some of the lines were very well written - with a potency and sadness - like how everything was designed with a purpose it couldn't fulfil anymore. Somewhat Shakespearian.
Some points would be that:
Some of the areas weren't clear - especially the area to the right of the bus, and I wish the controls were more contextual - like if I click on an area exit, even with "Talk" or "Use" it just assumes I wanna leave.
Other than that, cool puzzles, great dialogue, cool soundtrack, overall fantastic.
