What a cool idea! I love reimagining of older titles like this.
This seems like a concept that could easily be polished into a successful mobile game! Have you considered it?
There are a few suggestions I'd like to propose:
I agree with the comments about the restart feeling too long, specially when there is a bit of luck in the road layout at the start, if this took half a second, maybe the feeling of unfairness when getting a bad road would be minimized.
I would also consider roads without random elements, I think being able to retry the same road could allow you to pump the difficulty even higher.
This is a minor gripe but, I feel like the walk time between the start of the level and the duck getting to the road could be bigger, sometimes I felt like I died before even having the time to mentally process all the obstacles I would need to take into account. Another solution to this could be the duck starting still and only begin to walk after a button press.
That being said, these issues did not spoil my enjoyment and I think this has a lot of potential as a full release.
Cheers
