Well, after working on it for a few hours, I have another build for you! Two in one day. I have collision detection set for when you hit a wall, the player sprite disappears and you get two options.

I will this however, this game is tiny compared to my older version and I'm not even really using any variables yet, so I'm not sure what I was doing the other time, but I can say I'm having a lot more fun because I'm not under such a huge constraint to have variables available.
Heres the latest build:
