It's quite a challenge. A good way to adjust the difficulty would be to give more fuel or that the fuel is only affected for shooting at hard to expert or sth. I felt a bit betrayed being unable to move so fast in the game. It feels like I don't have much control over my movement. Otherwise the gameplay itself is really fun.
The game would level up with particle effects, which are not on the same opacity/ same design level as enemies and collectables. Musicvise it's a nice Arcade feeling, but it would be good to adjust it slighty so it won't get too annyoing and still has the retro feeling.
It didn't feel much of a rewind, more like a inverted shooting, but this can be interpreted either way. All in all it's a fun game und you did a good job!
