Really nice idea and art style!
Unfortunately, I got stuck as I couldn't eat the crisp that the dog dropped at the beginning :(

Same for me, and it happened each time I restarted: once the chip drops fully to the ground, it becomes impossible for me to get it to highlight. Only if I'm fast enough to eat it when it's still a little higher above the ground can I do it, so something seems to go wrong once they're fully dropped.
