This game is back on sale again! Though not it's lowest, still a great pick-up for a dollar-ish. Highly recommended to play with a controller.
Superflight is an intense, easy to learn wingsuit game with an infinite number of beautiful procedurally generated maps. A great game to relax for half an hour and chase your latest highscore!
Alright for $1.20, a kinda neat peaceful flying sim. Nice to relax with, and definitely easy to learn, hard to master. :)
