As said in the title, it was a 3D platformer that I played probably a decade ago on Google Chrome, through the Chrome play store. You played as a (cartoonishly proportioned?) young kid, and you shifted gravity with right click, when you did, electricity shot from your hands down to the floor, and you could spin the world however you'd like. The levels I remember having a dark metal design to them, and the final boss was a woman, maybe the one who lead you through the levels? This is fuzzy, but i think she didn't actually want you leave, she gave you your powers but was hoping you'd stay with her to keep them. I definitely remember that for the actual fight, she would shoot seeking missles at you, and you'd have to maneuver around to get them to hit her instead. Thank you for any help you give!
