2DGameWallBorderExample

I created this game to show an easy way to create borders or walls for your 2D games in BASIC. This game only has one level, but it should not be too hard to create more. I want to create a version using sprites, since the sprites commands do not have an easy way to create walls for your games I am attempting to come up with something that will work for me. I'd like to share what I come up with. I know this is very basic, but it's just a starting point. With the sprite version I want to try to add a more fluent movement to the sprite.

Hi,

Just wanted to share a simple one level game that shows a simple way to create walls/borders in your 2d game. The game has only 1 level, but it shouldn't be too hard to add more. I want to make another version using sprites, but time will determine that (free time that is).
