Hello there,
Welcome! The language
Lua is designed to be simple to use, so it's probably a bit easier to learn than C/C++.

Right now, DSLua isn't as friendly as VB, and you have to know a little about some game programming concepts (tiles/sprites/resource-conversion..etc). But I am working on making it simpler in the future. Feel free to give it a try, and post your questions and comments if you have any.

Have fun!
