Good game! What I enjoyed the most was the inverted gravity mechanic. It's a great idea, and I think you should base the entire concept around it, maybe even add left and right gravity to walk on walls, etc.
Sometimes, right-click has trouble working properly, especially when pressing other inputs at the same time. Also, you can skip entire levels by just flying around while spamming right-click.
However, the game is fun and has a solid concept, so great submission!
