the room spawning mechanism for the dungeon is on a 8x8 grid with the maximum room count of 35, out of this at least one altar and shrine should spawn (but its not distance based). Maybe I put the probability values of the altars and shrines too low (that's my bad). But thank you for trying out the game nonetheless. If you replay (if you have time or don't mind) the dungeon layout should be completely different! Thank you for your feedback!
