Fifteen Monsters All In A Row

You are in a cave. You don't know why you are in a cave. But you are in a cave. The walls glow unnaturally, casting everything in a pale blue light. Water drips from the ceiling. Puddles as dark as blood cover the floor. And ahead of you you see fifteen monsters all in a row, standing between you and whatever lies beyond. Freedom? Fortune? Fame? Or fifteen monsters more?

A couple of years ago, my niece (then 5) and my nephew (who was 2), wanted to design a computer game, so we designed a computer game.  (They're 11 and 8 now) But anyway, here’s  Fifteen Monsters All In A Row, a computer game about fifteen monsters all in a row.

(Please note: I made this a while ago and there's probably some spelling mistakes and counting failures in there somewhere. Sorry about that. But the main game itself definitely plays fine.)
