Thanks for the feedback!
I really like the idea of passive mastery xp, I'm thinking I could make it, so you get some % of your best gain while dead, so If you wanted to play more idle, you could just do runs once in a while to increase your best gains.
And speaking about the drinks is the problem, that they are annoying to refresh all the time or is the bigger problem getting enough money to sustain them for a longer time?
