The concept you have outlined is different for 2 reasons in my mind: 1. there are no golf games that i know of on TDC in the last 2 years+, and 2. this isn't actually golf, but shares some of the ideas of golf games.
This could be really good, and addictive, to play... so i'm favouriting!
(BTW, i stumbled upon this randomly - i've not checked up on the Projects section for a while...)
