I have been testing out your beta version. I really like the game and the many possibilities of your concept and growth with this business model. Hint: You could also possibly market your designs to every golf course across america and europe to pay a fee for having their course designed on line for play.
I have also found that when you hit shots far off line the game grinds up your PC resources and freezes your explorer windows. Attempts to shut down the process is difficult. I know this is beta...and you'll get it figured out.
My PC: 2 Gig processor with 1 gig of ram.....so this shouldn't be a problem on my end. Hope this info helps. You still get a positive review on my upcoming blog post!
