Movement of the protagonist made absolutely cool. SFX sound for driving would be great. Use either louder or a different interval when jumping.
Soundtrack beat in tune with the game play.
Visual and auditory feedback on contact with the information computer.
It would also be nice if it worked not only with WASD but also with the arrow keys (left-handers).
Jumping movement very pleasant!
Feedback on death blatantly cool!
Puzzle combinations very well thought out and animating.
Basic idea excellent!
