After feeling slightly dissatisfied with other videos on unlocking the donkey (no faulting Groundhog Returns without tilting the control stick/left + right on the keyboard), I went ahead and found a method that allowed me to beat it 2 times consecutively, whilst meeting those conditions.
I have edited the video to add tips at each step I think to be crucial (although I didn't know how to add text in Vegas initially, so the editing on that side is a bit rough).
Let me know if you it helps you, or if you have tips around video editing.
