You went in search of artifacts into the catacombs. But you stepped on something and got trapped, you are not the first one to step on this sinister stone, judging by the skeletons. But it's okay, you don't lose heart, since this is not the first time you get caught in such traps. First you must look around, perhaps there are artifacts here. Then you should search these catacombs, maybe there is a way to get out of this place. Basically, you are restricted in space only by metal grates, if you remove them, you can go further. There are keyholes next to them, you probably need to find a key to break free. Yes, all this happens in the new flash game Punishment Chamber Escape. Well then, good luck!
