Hi! Programmer here, first of all, thank you for the kind words! Now, we made the game with considering people going to know how to play roulette, but yeah, I definetely could have made some tutorial :D. And for the dialogues, the thing was we were adding them like 15 minutes before the extended deadline, so I didnt think about them anymore :D
Once again, thank you very much for playing and the feedback! :)
