Hi, so I have four questions. First, for the provided type-effectiveness chart, what do the various things mean? I assume the red minus and green plus are ineffective and effective respectively (Edit: And Black X is obviously no effectiveness), but what about orange minus, blue plus, grey X, and grey box? Second, is there any way to reset EVs? Most of my team has pretty bad IVs so I feel like I'm gonna have to EV train at some point. Thirdly, do I at any point need to stick with Red's team? Do I need to keep any of Red's main party in my team at any point? I'm asking because during the Lieutenant Surge on the S.S. Anne arc we got thrown into the ocean until Poliwhirl evolved into Poliwrath, so I'm concerned that I may be forced at some points to get different member's of Red's party if I switch out to different Pokemon. Lastly, how long exactly is this game? The main post said that Kanto and the Orange Islands are all that are implemented, but the FAQ mentioned Alola. So, that kinda confused me, unless Alola is part of the Orange Islands in this game.
Edit: Oh, and also, can the transforming Eevee actually transform between Vaporeon, Jolteon, Flareon, and Eevee like in canon Pokemon Adventures, or is that not something that was implemented?
