The hair pin is a moon indeed, but this design was made horns-like this on purpouse ;) We are super happy that you noticed this detail!
About controls: yes, I see what you mean and we still considering what to do with those controls after that much of feedback lol. This made to production because we as a developers mastered those controls duting the development and it felt pretty fun to us. However, We are thinking about reducing or cutting off the inertia and maybe scaling collider a little bit so character would not fall of the edges so much. We will totally try this with grid based controls, see how it plays.
On music it could have been done in a million ways, but we enjoyed beats our sound designer proposed and didnt’ bother to iterate it that much. But yeah, this game would definitely be enjoyable with acoustic instruments like in Journey. We only had 3 days and a lot of work to do, so we didn’t have a lot of room for experiments or polising ;)
Thank you for your meaningful feedback, it’s really good to see people analysing the game and sharing their feelings and opinions like that.
