Kafkaesque game by Aurel Bílý and Eido Volta takes you to a castle or casssettle, whatever, where you soon find out that this is a place you may never leave - so you were told by the strange mask. Do you believe it?
And remember, the cassettle keeps its subjects!
So, you are in a room with a talking mask (looking a bit sinister) and the mask isn't very helpful - answers to simple questions in a vague and complicated way, and the only thing you are able to grasp at the end of your dialogue is that you can solve all the puzzles you want. Great.
The only item you get in the starting room is an old fashioned cassette tape and immediately appears two cassette players in which you can insert the tape(s) and play, rewind and stop them. The puzzles you need to solve inside mystique cassettle are music-themed and tapes are your tools - there is always visual clue, too, luckily. Later you need to combine two different tapes - you can use both players at once. However, even if you solve all the puzzles you find, you may stay stuck in a loop...well you were told that the cassettle keeps its subjects! There are ways out though - the games has 4.5 endings - can you find all of them? Can you break the loop?
To interact use the mouse, to use the cassette tapes as well, to move the camera arrow keys or WASD. No autosave.
