Yes, I like FPE, I'm a big fan of FPE, but in my opinion FPE is not a good matchup for Pillar Chase 2, one of the most wanted monsters by some people is Miss Circle, but, she doesn't fit to Pillar Chase 2, the same goes with Miss Bloomie and Miss Thavel, the rest of FPE characters are just a bunch of kids, the only characters that I find fitting to Pillar Chase 2 is Alice and FEN.

Plus, the BladeNinja and some other devs don't like Miss Circle, and there is a high chance that they don't like an entire FPE fandom, so don't expect them say "yes" to an idea related to FPE, the same goes with Murder Drones.

But, FPE characters instead of being playable monsters instead can be skins for already existing monsters in the game, like PCX, Fogborn, Forest King, etc.

Idk about FPE being in other similar games like Devil's Dawn or Camp Cataclysm, but FPE definetly doesn't fit to Pillar Chase 2.

Note:

Another reason why FPE shouldn't be in Pillar Chase 2 is because we already have a game called FPE: S, and that game kinda looks like Forsaken, Sonic.EXE: The Disaster and Pillar Chase 2 but with FPE characters.
