This is actually a cute game. Took me a bit of trial and error to figure out, but that is my experience with most games. Even with a will well written tutorial it takes a bit of trial and error to get the hang of a game, so this is not criticism of how you explained the game. I did have a question, wondering if I missed something.
So I first played a little bit of the game in browser. Thought I finished the tutorial, got called away from computer. When I came back I decided to just download the game. Thinking I already finished the tutorial part, I clicked on skipping the game tutorial. Then later I discovered I can click on women behind the deck in the lobby (sorry I don't trust myself to spell their names correctly). It brought up a menu labeled shifts, and I not sure to do with it. So did I unknowingly skip over the part were they explain this?
Side note: I did also encountered a bug which someone else explained in the post below this one. I replied to that post explaining I encounter the same bug with a different version then they were playing.
