thx kindly dudes

Oh yeah, although I'd like to create more detail in the tile mapping, zoom scaling, sprite management and path finding (pj?).
bigsofty, the baddies are there, almost, although the wall collision is a bit clumsy. That is why I tested two characters for bitmap loading and I'm hoping to add many more, depending on available run-time memory. I need to test LOADANIM, to increase level loading as currently it takes awhile to load individual bitmaps.
Treasure, pickup, quests, doors, etc will depend on game-play, which I hope to make interesting and not just a maze game. Perhaps some level may be hand created, like with Mappy. I need to find out the technical limits mentioned above before I start on this. I've even opted out of isometric for now.
peejay, is the path thickness modifiable? For example, 3 tiles wide yet 1 tile for the wall. Entry and exit points would help. I'm not sure what the bug results, but I'd be happy to update the code in future.
