Thanks for playing and the feedback! ❤️ The spawn rates aren’t completely random. There is a weighted pool of possible things for both the big and the small question mark for each of the six levels. Both can be good or bad (or or sometimes somewhat neutral) but I think giving up any more information about them would like moot the point of having them be ”hidden” at all. One of the big ones is always the staircase and the rest are chests or bosses (and later on or rarely allies). The small ones have less variety on possible spawns based on levels (well except for different mobs) and also offer less impactful rewards in the form of pills.
