Big step forward

Managed to fix the bug that stopped the player switching levels (which turned out just to be a simple maths issue)

Added additional control options  of arrow keys & awsd keys.

Added button's for controlling assets 

Changed the core level's logic to a parameter controlled system so level switching is data driven meaning adding levels is simply a matter of adding to the maps array. In theory the core of this game code combined with the tile map editor , an asset editor and a character editor could make a simple tile based game engine which can be extended using QB64

Still need to add assets, characters with their logic, a scoring system plus game save & load options.
