Oooo do you mean having random numbers of tombs the player can open per day, am I understanding that right? The suspiscion stat was meant to limit the number of tombs players could open, or at least make player choose which graves they open more carefully because too much suspiscion leads to another ending. But I agree, the game could be more challenging! Maybe with puzzles or some guard obstacles between the player and graves hmmm...
Thank you for your input and suggestions, and for playing my game! (ㅅ´ ˘ `)
