1. First of all, there's no link to winsetup created in programs folder, which may make it difficult for players outside AGS community to figure out how to configure graphics. I would also suggest to add "Run setup" option to the last installer's page (if installer's engine allows that).
2. The LMB/RMB interactions are largerly inconsistent. Although quick "tutorial" on startup teaches me that LMB = interact, RMB = look, in reality RMB acts as "use" on many occasions.
3. Player can open main menu with Esc key, but can't close it with the same key.
4. Sometimes the player character fails to face the conductor when talking to him. To reproduce - stand to the left of him, then click on him to trigger conversation).
5. The middle door in the second carriage lacks "walk to" point; unlike other doors player does not come close to check if it's locked.
6. Barman keeps repeating "No thank YOU mr Lang" if you keep clicking on him after all dialog options are used, which does not make much sense on its own.
7. The main character's voice actor is ssss-ing really loudly in his mic, this makes me cringe. Also barman's voice is one level quiter than others, I think.
8. The opening&closing inventory produces very annoying sound, IMO. At first I did not realize it is even related to interface and thought the door has opened somewhere.
