Regarding the quests - I didn't clock that they should guide my build, so I must have missed that. They were something tucked away in a menu that claimed to give big rewards, so I clicked the button but then I didn't really ever understand whether they were still active, or experience any reward feeling when they were over. I guess they gave me gold but I happened not to be looking the second that the number changed? Maybe if they were somehow on the screen counting down and showed off the benefit I earned on completion, maybe I would have been more inspired to focus on that system.
But I likely didn't notice the reward because I was probably playing like a bad starcraft player who floats 2k minerals without realizing, and that's why I didn't notice the influx of gold. Your core player may automatically understand these. I clicked the game because it said "15 minute runs" and "roguelike" whereas most of your players are probably familiar with autobattlers and idle-adjacent power-curving games. I had to think for like 15 seconds what you might have meant by TFT, if that gives you a sense of my familiarity w genre conventions.
