Useful feedback thank you! The level design was a little last minute and we would do things a little differently next time. We don't want to give too much away so as to encourage exploration so we didn't want quest compass style elements. Perhaps smaller levels and a minimap. And yes differentiation in different parts is a really good idea - perhaps using different obstacles and scenery in each area.
Story mode is the easiest for those who just want to experience the story. I think I'll add a top tip for the post jam update. Thanks again :)
