Probably something in Game Maker in 2006 or 2007.... or 2008, can't remember. It was something about moving a bear around (which then got 3 sequels).
Most of those games were short and simple, only having a weekend of development time. For resources, I used evything that Game Maker offered (I really liked the explosion animation) and what I had collected from the internet. I suppose these games are in a CD somewhere... Waiting to be remade...
For other earlier games I used a programming language/engine named "CoolBasic". Made couple games with it until I moved to more modern/advanced tools. It was a nice way to learn more programming, but as a game engine, it's kinda outdated. But you should try it anyways!
