I heard that Really? Really! plays like Phoniex Wright: Ace Attorney. That sounds awesome
It is a parody of it. Really? Really! is Kaede's arc. Basically you find yourself entering her reality where you have to correct discrepancies in her memories (Kaede has lost her memories), by collecting keywords (fragments of correct memories) through different events in the game. For example, the first memory you are at school with Kaede, but Itsuki is a female, when really he is a male, and Rin's best friend. So, when you go into Really Attack! after that scene you choose the keycard that proves Itsuki is a male and you correct her memory and move on.
It obviously becomes more complex than that, some even involve specific events that happened in the manga or the anime, that you would have no way of knowning without having read/watched it. Also you'll eventually run into split paths where you'll end up running into a Really Attack! scene where you do not have the correct keycard, so you have to choose to skip it until you find an event in the game where the correct keycard is given to you.
It is a difficult game because not only do you have to have some decent knowledge of the Shuffle! universe, you also have to be able to desern what the keycards represent in Japanese, plus you have to play the keycards at a correct time during the Really Attack! (in other words play it at a certain time when Kaede speaks about the memory in question.)
I haven't been able to find a guide on the internet either. You could always go through by trial-and-error, but if you fail to provide the correct keyword (five times I believe) in one day then it is an automatic Game Over.
