Woah what a game! Amazing work, this is the best jam game I've played so far. Really impressed with the amount of polish in such a short time! The art work, the controls, the sounds, everything is beautifully done. I felt like I was playing a demo on the next big indie game on Steam. Not only is the gravity mechanic cool, but introducing the anti gravity stone throwing unlocked a lot of potential with game design. I believe if you keep working on this and add more level manipulation with the anti gravity throwing, you can turn this thing into a hit! Wonderful job, keep up the work!
