Cool mechanics and ideas but I found the physics to be really annoying. Couldn't make it past the second level even though I'm pretty sure I know what I'm supposed to. But the one of the five balls kept falling off the tiny button. I'm pretty sure I was supposed to get the balls in a line with the environment but getting 15 was just too hard. One or two always fell off. I tried to take a few at a time but then I had a timer to deal with.
