SImple game i did got a few endings but just pressing keys on 1 screen to get an ending is not really gameplay to be honest.
Try to put a bit more effort by either let the player do more stuff or at the least come up with a story that engages people.
That being said you made a game in 10 days and submitted it, not everybody did so that is a win. keep trying an learning and i am sure you will improve your games.
One thing tough what would have been very simple to do but i a game that need restarts is invaluable is a restart button so i don't have to refresh my browser.
