The Prisoner is a fidget video game by Louigi Verona.
The goal of the game is to serve you prison sentence in the dungeon of Prince Abubu. Each passing second increases your score, and once you reach the goal score - you have served your prison sentence. However, you can make it happen faster if you collect treasure. You also need to eat. If your health goes down to 0, you die. Therefore, the game forces you to pay at least a little bit of attention.
