It's a 2dcg visual novel set in medieval/ fantasy world where the main protagonist lives with his sister in a shed and they go out hunting. There is a scene where they both take bath in a (pond or river). There is also a (festival)? where you have to pick someone as your (partner)? by giving them something (a rock or jewelry)?

I think at the beginning of the game, you have a dream where you are in a (dungeon)? and there are naked statues or something

There is also a knight character who trains the main protagonist.
