It's cute, until you get to the stages where it gets where you need to be very precise.

Arrow count doesn't decrement:
66 f5 0d c1 63 05 62 04 62 05 61 f5 0d =>
66 f5 0d 02 63 05 62 04 62 05 61 f5 0d

You can hit the dude with no penalty:
d0 30 20 80 4d d7 20 80 4d =>
47 30 20 80 4d d7 20 80 4d

It was a quick look, don't have time now to make a "health doesn't decrease over time" one. Will later, if someone else doesn't do it beforehand.

Enter iddqd on the menu screen to get all levels (!not perfect win!) and all achievements done.
