For all the ones who ask , what u can do to get all the achievements the only thing i can say is explore the map a lot, anytime u find a waifu there´s near some chest on each map u need to discover 7 chest to complete saddly i only can complete just 2 maps =/...

Looks like the same Demon Girl 3d model from the pc game Overdungeon.

Dragon Ball Z Kakarot came out earlier and you can fly in that....its an RPG game as well an anime and you can fly around freely....way to make unreal claims.

Yet there ain't any, huh?
