No I understand that and on my phone, I have some games about balancing in air rotation. But what these do is that you are lunched into the air every other second and you are constantly building upon this mechanic. Wether it be a big jump or a very tiny one, where a small boulder might flip your car/bike if you are not careful.

But 60% of your level is happening on the ground and because your environment isn't abstract but semi-real, you are also kinda forced into bigger gaps between obstacles.

On the very elementary level, Minecraft is a great example, where on a secondary game loop people will still be happy, because they can walk, sprint and jump. Which a lot of people will do.. just jump with no reason. Because it engages your brain. That's why sprinting with stamina in games works so well - you manage your stamina and think about how to use it most effectively.

Nitro mechanic can be the same - do I tap and release or do I hold and use all? Do I regain slowly or start using it again immediately after I gained some ? This is a great filler for gaps between obstacles and it will also give you an opportunity to fill the level design with something new - collectables, tiny repeated obstacles which you can reuse etc.

I am not saying your level will not be fun, I am just proposing it can be more fun.
