I have noticed a few things. with this game.
1, when you buy the crowns with diamonds. they get equipped but have no healing factor like they are supposed to.
2, for the special weapons, from what I understand, you can either purchase these weapons with cash or diamonds. but for what ever reason despite having the correct amount of diamonds on me. I cant buy weapons. only allows with CASH despite having both options listed.
3, The most annoying bug is that when buying any of the guards. they always seem to get stuck on room 14 and will no longer follow you beyond that section. or they randomly just disband and leave you.
