i think you should have a project that includes everything needed to start up a game, but is simple enough to edit. for example:
* one graphic sheet with one of each tile category (solid, hills, and top solid) and a basic sprite
* two framesets, one for the tiles and one for the sprite
* a tileset and defined categories
* one map and layer including the player sprite
* all necessary solidity definitions
* a sprite definition for the player sprite
this way, someone new can just tinker with the graphic sheets, or enlarge the map, add new layers, ect. to quickly create a new project rather than having to set everything up. this would be great for first timers.
on the message box issue, this is the message i always get no matter what i type in(see bottom)
