Monkey-X - RPG - Scrolling platformer - Mining.- Game Template

' version 7-12-2015.
' Template.
' Scrolling platformer with RPG features.
' Based on the scrolling platformer with vines
' template on my Monkey-X blog.
'
' The mapwidth variables can be set to large(200+) or 
' small(100*100) maps. There will be multiple mines
' placed and populated if there is enough space for them
' on the map. (This version runs fast enough on low
' end laptops with maps up to 320*240 - there currently
' is no LOD implemented.)
'
' Game :
' Travel down/explore the mine.
' Has mining eggs feature. Hunting for meat.
' Monsters lay eggs. Only one monster hatches from a egg
' if there are no other monsters nearby.
' Monsters/breeders do not attack.
' You can pick up the eggs. Kill the monsters for meat.
' You can place an egg on the ground and a monster could be
' hatched.
' Eggs can also spawn Deathwings and they attack/hurt you.
' You have health and if zero restarts the game.
' p - Place egg on the ground.
' t - Pick up egg from the ground.
' Space - Attack with spear.
' curs left/right/up - move and jump.
' 
' Thinking of adding automated machine gun nests that you 
' can place/move around and they kill the flying monsters.
'
' Mood of the game at the moment is : 
' Monsters live in an old abandoned mining area. You can 
' mine meat/eggs to make a profit. Monsters
' have been seen flying nearby mines attacking people.
