I got an idea for a screen for Frank the Fruit Fly. It is basically my Explosive Diarrhea game. If you're not familiar with that, the goal is to cross a minefield without stepping on a mine. Stepping on one will send the player back to the left of the screen to try again. So basically, remember where the mines are and don't step on them. Since Frank only has to cross this once, I don't really need to reset the mine positions.

Right now the randomly placed mines are visible, but they won't be when I'm done. I have four. Should I add a few more mines or keep it the way it is? I don't want this to be easy, but at the same time, I don't want it to be hard. What do you think?
