Nice clicker game! I love the message of smoking being bad and the player as a villian. The economy balanced pretty well. What would really help is more visuals and theming of the game because it just seems too generic. The UI has kind of a windows vibe but that doesn't really fit the theme of the game. Also clicking to sell a pack becomes not worth it at all after a while, there should be more upgrades to keep that somewhat worth doing. Other types of side games or combos would help add depth to the gameplay. I think this is a very good framework that could be built out nicely with more assets.
Another thing I noticed, it should save progress in local storage so players can leave and come back, this is a small feature to add that would help a lot with player retention.
