Gameplay loop is pretty simple you spawn at the top of a small procedurally generated map with a wingsuit and get to fly to it. The more risky you are with how you fly the more points you get. Their are portals in the map that will teleport you to a new area, if you fly all the way to the bottom of a map it also teleports you to a new area.

It's easiest to understand if you just watch like 1 min of gameplay: https://inv.tux.pizza/watch?v=YfRBsP_TFLA

It's a very simple game which is what I love about it. The difficulty is completely up to you, if you want to just relax and fly in a super roundabout way to view each map then go down to the bottom and go to the next map with a 0% chance of death that's easy to do. If you want to challenge yourself and fly through as many ultra-tight holes as possible you can also do that. I originally saw it in the background of a video essay online and picked it up. It's perfect to play while you are talking to friends about random stuff as you can still focus on the conversation while playing the game and it's entertaining to watch. Though the conversation will sometimes get distracted with everyone passing around the controller trying to make it through a super tight hole.
