- nice graphics
- the ‘car is now driving’ musical score gets repetitive while working through the solutions
- not sure if it is intentional, but the simulation seems to be non-deterministic, you can just click rewind/play and get different outcomes.
- interesting physics puzzle
- given that seeing were on the play track the scrubber is helps with IDing what you want to change, if there was a way to have the full track viable and the scrub-bar at the same time without the transparent overlay, it would be a nice quality of life improvement
- adding some crash, rev, wheel skid sounds at appropriate times might be an interesting addition.
