This is just a free exploration game; with a large void, almost endless. Discover many different types of platforms. I had this once in a dream and I wanted to recreate the feeling. The red box is to anchor yourself. Gravity by default is none, but if you equip the red box it changes the gravity to low gravity. If you equip it for longer it goes higher and if you unequip it you go back at that same speed you stopped equipping it at. Just a note.
