I can only just understand this
In the sense when you start the game its easy
and it gets a lot harder and harder by a simple change
it would have had a better effect maybe if the title of the game is not going blind
and at the end you find out that the dog you where playing or jake was going blind ?
idk
maybe even a counter for how long it took you to finish each level so you have a visual representation of how much more you had to struggle
but then that could be making it to complex who knows
for me you accomplished your goal though good job
