I think this is a solid start to the game if you plan on continuing it or making another one someday. It is short and repetitive but a couple simple things would keep the player playing more. A clock somewhere to show how long you lasted or a score would help as well. An ability to pick up some health or something could also work with the clock to try to last longer. I like the message at the end though. I did a short Let's Play of it here: https://www.youtube.com/watch?v=7Em1DY8CW_U with more of a review while playing it. I do like the overall idea and think it could be a good game going forward but that is entirely up to you. Keep up the good work though.
