A few notes: tying aiming and camera together is awkward, and the lack of a way to view the hole before making decisions is a bit frustrating. I did like the automatic power bar, it was easy to work with, though I'm not sure why you mapped shooting to RMB and didn't use LMB for anything other than menus? The physics on the holes needs revamping - I frequently bounced out of the hole when I expected to drop in.
The tutorial mentions skills, but these aren't described in the character select. Likewise, the plot from your page here doesn't seem to be in the game!
A scorecard for the end of a course and a way to review my scores so I could improve on repeated plays would be a great addition.
