The inventory system we've been working on under the hood for quite some time is getting close to being ready for testing. With the inventory system update we'll also be releasing more discs.
The current discs would probably be considered a bit over-stable when thrown flat, so next we'll be adding at least one stable, and under-stable driver, mid-range, and putter.
We've also been listening closely to new players who may not be avid disc-golfers, and as such want better in-game hints / tutorial. Our team has been hard at word putting this towards the top of our list and have setup a full game settings based hints system within UDG.
These hints can be turned on or off from the settings menu and will work on any course during single player mode.
