You present this game as "a 4th wall breaking RPG that makes its characters and the world surrounding them aware of the player" but this is not true as Alterna's inhabitants are not aware that someone from another reality interacts with them, you made the player be a guardian spirit, a bodyless entity from ancient tales who talks in Shawn's head, but this is still an inhabitant from Alterna, even if he is bodyless and talks in another inhabitant from the same reality's head, both the guardian spirit and Shawn are inhabitants from the same reality so this is not 4th wall breaking as Alterna's inhabitants are not aware of the player as someone from another reality who interacts with them, this is not 4th wall breaking if they are not aware of the 4th wall, the screen, between them and the player.
Now don't get me wrong, I am not complaining, I like Numina, I just wanted to explain to you that the way you present it is wrong and so suggest to you to correct it accordingly if you want to be fair. ;-)
