This game can be done in Czech or English, and none of the resolutions required language.
Commencing blindfolded and chained to the floor was an interesting start to the game.
The light was low and it took us too long to find the keys to release ourselves, but once we (finally) managed that, we got going.
There were a challenging number and variety of clues and codes, but all completely solvable. We went over time. There were two in our team, and it may have been easier to meet the time with a slightly bigger team. But not too big because the game takes place all in one room.
The puzzles tested us and we needed several clues / clarifications, but these were live from the gamemaster (which was nice), not automated.
