SKYE is a student project I believe and sees you flying a plane around an island. You're given tasks to complete to further the story and it's fairly fun but very chill.

And at a certain point out of nowhere you're told to go home and the game is over. Which is a shame because I'm sure there's more that I would have liked to see from the game, but it being a student project I guess they ran out of time to do more.

Oh did I mention it's free on Steam? Well it is.

So if you've got an hour to kill and you want a chill game then this is certainly one
