Enclosed the screenshot.
Somehow the user interface is a bit confusing for me, it's not fully clear what to press or what to do - especially in the garage, I don't know how to exit from there and return to race.
I do not fully understand how to start a level by a code. It took a while to figure out how to enter numbers in the first place, not very intuitive. Nevertheless after entering a code it always starts with first level here. Can you explain? Moreover I would like to be able to enter the code by the number keys and pressing return to start, at least optionally.
You are certainly right but the distance of each move is too big and so hard to deal with in my opinion. So maybe less distance between this "jumps" would also make the movement a little bit more fluid. It is causing the game to be much more difficult than necessary.
The walking animation should be improved. It is looking very weird.
This is a very nice clone, too:
