This is a platformer where you can rotate the world, you're in. You collect all the spheres to advance to the next level. I did everything including the music, game development, and SFX. This is the first game I've made since learning unity 3 months ago. I would like to add more levels to this so if you want that let me know. If you have any tips about game development that would be very helpful as well. Thank You.
