You're supposed to take some of the tickets from the other bidders to get more, and theres actually no background music lol it's the walking sound effects and the ticket placing sounds (I made them drum sounds). You are right tho that there should be an option to disable the sounds and I should definitely add that and maybe a clearer explanation for how you steal tickets in the intro.
Also could you clarify the game running part? should the game close if it's been running too long?
Thanks for the feedback!
