This is a neat story you've put together! the controls were easy to use and the artwork is unique!
It was difficult to tell when the character was getting hurt/ time was being removed because there was no indication on the player character. Some sort of indication that you've been hit (not necessarily hurt) might be something to consider, to communicate to the player that something bad has happened. Also the button didn't react to being pressed so I couldn't tell if I had pressed it or not. Having the button get a little shorter in height once it was touched would make it look like it was pressed inward.
Other than that, really liked playing this! Nice work making a cool game in a short period of time! :D
