    I give this rom a 5.5/10

    i think there are a lot to fix:
    1. the abilities such as competitive doesn’t work so do other abilities especially the newly introduced ones.
    2. movesets: some Pokemon lack the proper movesets they’re supposed to learn, example the Talonflame line: I have a flechindr that doesn’t know flamecharge.
    3. lack of new Move sprites/animations: some of the animations just borrow the already existing ones like : moonblast, aqua ring, and X-scissor.
    4. lack of other Fairy type moves.
    5. other Pokemons from Gen 5-9 aren’t fully supported.

    i urge that u fix this matter to make the game more fun to play with.
