Our artist work on 3d version. Will see later how it fits in setting.
Question about palette arises. We must answer it as soon as possible. Palette make mood of game.
Hand drawn pictures good for prototyping and wait screens. But draw entire landscape is very time consuming. We have time (game developed as hobby/part time) for anything. But gameplay is main priority.
Graphics good to have, but it too time consuming, but fun also.
