Definitely should have cleaned up the leaderboards at the start of the game to make things clearer :/
If you look on the left before first launching yourself forwards, you'll see a Leaderboard !
The objective is either to fly through 10 000 meters with the lowest time possible or to race to the furthest distance you can reach in 200 seconds !
(you can gain a ton of speed by launching yourself off of terrain with [S] + [Spacebar] too, regular dashing doesn't give you that much speed)
You can switch between those two end goals with the [Switch Mode] button ^^
Glad you liked the art and music though <3
