hey thanks for the detailed bug reports -- i'm currently wrapping up another game so i haven't had time to figure out what's going on but these will be useful in the future!
If you do get back to this, a seed feature to share maps would be excellent! I’d love to be able to save tricky seeds so I had a stash of hard maps I lost at for a rainy day!
Another feature recommendation I would add besides autocollecting shotgun and shell and being able to mark rooms with hazard colors or icons, is a number of rooms visited, seen, and unseen remaining. The number of times I have counted rooms because I am not sure if I missed a collect prompt or haven’t found an isolated branch is too high.
(And there are the occasional few edge cases where knowing the number of rooms remaining makes it easier to spot a trap situation!)
