You drew these graphics yourself? That's amazing! Keep working on it, and you'll have a great game. My advice is to hide the text box asking the player if they want to do something if they move away from something like a generator or a locker and to move the instructions to the middle instead of on the top left since it is blocked by the player's health meter. And like BUKKBEEK said, I was not able progress further after I hid in a locker, so I was not able to finish the game, unfortunately.
Nonetheless, I think this game has great potential. I loved the comic book opening as well.
