Too hard for me! Either expand the cave or slow down the "plane" or "train"

I want to see a speed run of this.

VERY HARD !!1

A good game but
1. It's not a train. I read the desc but damn
2. If it was a plane then you should've called it plane game
3. The controls are slippery
4. Because of that, it's too hard

Can you fix these please?

EDIT: Well because of the lags on PS4, it's easy to play on PS4 so uh yeah. An extra star for that?

I feel like I spend too much time doing full 180's just to slow down, so the game lacks a certain flow. I think the acceleration speed and level design don't compliment each other well, so tweaking that (i think) would give the player a lot more agency in the environment. But, for a game made in 2 hours, I'm impressed. The idea itself is neat, it just needs tweaking
