It's definitely fun to solve the puzzles. Especially if another player is needed for the solution. I have a recommendation for the game principle and the possibility of simple cross-language communication.
Only after about 3-4 hours of... play the air is out. Everything solved and all challenges overcome. I hope that there will be updates or at least the possibility to create your own puzzle for this game. Apart from that it was really a short pleasure
