That sounds like s cool game. I am also in the proces of making A Mine-Map-Game. My game is called Team Shot. It is sort of a mix betwean Black Ops, and Minecraft. It has all the Black Ops wepans but is played in a bunch of minecraft maps, like Jarreys tree (CartainSparklez) a castle that I made, the nether, a cave, and my favorat a modern town. At this moment I have about 2 maps, and I am looking for someone with Minecraft PE to help me.
Hope this gives you an idea for a mini game, Team Shot is copy Right Budy8760 Gaming but you can use it as a small idea.
