It almost felt like I was making some trick shots in basketball. You both did a good job of increasing the difficulty and including elements gradually. I hadn't realized at first that I could interact with a few elements (such as changing the direction of the conveyor belt, or clicking on the portals), so it might be cool if you added some kind of visual indicator of things that are interactive like hover states or perhaps a subtle flashing border. Besides that, it was a lot of fun to play. Nice job!
