Cool little game! I know it's not easy to do 3D games (and more difficult in gamejam) so it's a good thing that you have a finished project! Here is some suggestions to improve your game :
- Different level design, because right now it's just same walls and same ground
-Add a ball rolling animation
-Fix this camera or re-think the camera because a moving camera in a second person game is definitely not the best choice ^^'
But I'm pretty sure your nest game will be awesome! keep doing jams!
