Wow, I didn't think that the game would be open world, the game looks great and the music is nice. Great idea. The only think I not sure if I liked it its the control of the player I can't figure out what it is. Anyway, it was great!
If you don't undersantd there is a video of GMTK (sorry Brackeys) talking about the movement of Madelyn in Celeste, I know it a totally differrent game but I think it could give you some ideas.
