Got the end! That was sneaky haha. I still need to figure out how to open the other box (aside from brute forcing it LOL). The safe was easy to figure out.
It was a bit tricky, but totally manageable with some strategizing. I love and hate that it takes 3 shots to kill most of them, but your gun can only hold 2 bullets at a time haha.
Sounds like I still have some secret rooms to find, too!
