Ritual is a little music rhythm prototype about summoning a demon. It is meant for two players cooperating on one computer keyboard.
Each player controls four drumsAt the beginning of the game you first need to set the rhythm. You can set any rhythm you want. You just have to tap 8 times to set the rhythm. Immediately after that, another player needs to repeat the same rhythm by tapping 8 times.
Once he rhythm is set. Players are taking turns. Each turn consists of two phases: repeat and set the rhythm. In repeat player is trying to replicate the rhythm that was set by previous player and in set that same player is setting completely new rhytm for the other player. After each turn it is evaluated how well the player repeating the rhythm was able to replicate it and based on that evaluation points are calculated. The evaluation takes into account number of drums that were played, their variety and how precise repeating player was in the replication. When you advance to next level you open the gate for demon more and more. There are 6 levels of summoning the 6th being the final. Then you can restart the game and play some more :)
