Great game, lots of potential to be an extremely fun game! The acceleration and the lack of friction does add a lot of difficulty to the game.

Here I only have 2 suggestions:

• Maybe add some music to intensify the atmosphere. You can grab a lot of excellent free music in the Unity Asset Store
• I would say making this game into an endless game is better since you have the distance counter but it doesn't really serve any purpose.

anyway ty for your submission to Insane Game Jam :D
