Better physics and disc tracking and some hidden stuff — Trippy's Disc Golf Steam update #602362

This update is another update to the flight physics of the disc to try to get even closer to realistic flight pathing. In addition, added a 'trail' to the disc so you can actually see it moving through the air to have a better idea of where it went. Hidden stuff: Started to build the backend to the in-game shop to buy and use more discs. For those opposed to microtransactions, good news, we will NEVER have micro transactions. You will earn in game cash by performance to get these discs. Future maps will always be free to current game owners. The base price of the game might go up as features are added.
