I tried the game, it's an interesting premise worth exploring.
I think I got stuck at the chest puzzle, I swear I have tried every combination possible, even though I've checked every chest before hand I still get the explosion.
When I open each chest (saving before the puzzle) :
Chest #1 has explosives.
Chest #2 has Non-explosive.
Chest #3 has Non-explosive.
Yet when the guy asks me about the chests, if I give him the answers: explosive, non-explosive, non-explosive. It still gives me the explosion game over, is it a bug or am I doing something wrong? (I did try other answers but nothing is working).
