About the Harem, I mean if the MC can become a Pokémon master and catch them all, hahaha, seriously if the MC will keep all the girls in the end.
As for animation, I hope you try it, because the truth is that many games are good, whether it's renderings, story and so on, but they don't have animations and that's a big decline, which goes from being a Great game to a normal one, for that and more encouragement to encourage you to create animations, without further greetings and good luck DEV.
