version 1.76 glide game reworked, new content

The game mode 'glide' (choose from the pause menu/F1/gamepad 'start' key) has been reworked with new flight mechanics and procedurally placed rocks(different for each level) for the player to glide as near as possible without crashing to score points on the way down. Close to the bottom of the level, the HUD will display 'Round Over' to indicate scoring has ended. The first 3 levels have glide scores submitted to steam leaderboards, greater levels than that are local best score. Gliding works in VR also and supports head free-look, have tested with Vive and gamepad. Remember to start the game with the Vive controllers on and then you can turn them off if using a gamepad/keyboard to control. VR display HUD elements still need adjusting. The gamepad 'Y' button or keyboard F6 key will toggle on/off a VR HUD display of score,etc. In VR I tend to find the HUD distracting so I just toggle on/off when curious about my score. The new gliding mechanic is also available in Climb and Crystal Hunt game mode(press keyboard 'G' or gamepad 'X') after the level is complete and Explore mode. For these game modes, the player can gain speed/altitude by pressing keyboard 'X' or gamepad left trigger. Other various fixes also. Glad for constructive feedback on the 'glide' mode while still making fixes and adjustments and continuing to add some additional features. Thanks garcia_1968
