This was fun! The aiming felt good, and it was a nice challenge to try to get all the levels' holes in one. It did sometimes feel like the friction on the ball was more than it should be (the number of times my ball stopped at the very edge of a slope was too many to count), and I was a bit disappointed/annoyed by the empty sky that just sucked up the ball into the nether when a big arc would have been great; I'd have liked either a ceiling (like in the first level), or preferably, space to do a big arc if I wanted to try to get that right.
But anyway, nice, clean graphics, and a fun time. Nice!
