I loved the sandbox element of this game, as well as the arts (both 2D and 3D). The story also fits the theme and the ending was funny!
The only issues I had, aside from the movement that you stated in the game's description, is that there are no SE's (fireflies sounds would make the forest more "alive") nor a flap wing animation for the 3D Owl and Bat!
However, the game's scope is really big, so congratulations for managing to finish it in just a week!
