Should probably be add, not set.

Should use modern for loop.

Not even sure it’s helpful to allocate these on the heap. Maybe just Tile here instead of std::unique_ptr<Tile> some day.

Maybe, but now Tile is not simple stucture to keep the HashMap as instance.

Anyway, I will consider it in different bug not to allocate.
