Looks interesting, but is there a location
that gives directions or hints on how to play?

You might try this site or one of its links:

Download and unzip the game to a folder on your PC. There is nothing to
install, per se. Then just open the file called Glider.exe. Click Game New (I
think) and wait for it to open.

Basically, only two buttons are used: left arrow and right arrow.

Since you're already a glider pilot, it should come fairly easy to you i.e.
regarding glide slope, obstacles, etc.
