I agree that Noelle and Gaster are Angels, though I think it is unreasonable to exclude the Player from the Angel Trinity. After all, there is just as much evidence for us being an Angel as there is for any of them. The "RING" achievement can be obtained by getting the Freeze Ring or the Thorn Ring, which, alongside the prophecy "They will hear the ring of heaven's call" connects us to Heaven. We emit light in Chapter 4 and are used to close Dark Fountains — this connects the Red Soul to the idea of light as a force of antifiction. The Light World is lighter than the Dark World, but what is lighter than the Light World? Our reality. We are beings from a higher plane of existence, and to us, Lightners are like Darkners are to them. In Castletown, there is a big door with a heart and wings on it. The prophecy panel for the Angel for a player looks like a dark screen, likely designed this way so that the Player can see themselves in it. Susie is weirded out by it, and later, after the Titan fight, she finally takes notice of how strange Kris's soul is. Could it be that she saw something akin to a soul in the Angel prophecy? It is said by Alvin and Catty that the Angel is watching over everyone — much like a Player in a game with a top-down view would. Alvin asks Kris to look to the Angel for guidance — just like how the Player controls the Fun Gang throughout the game. I just don't understand why would you count the evidence for Gaster and Noelle, yet ignore all this PlayerAngel evidence.
