There was this tiny, short little guy. You could find different suits I believe; one was knight's armour and one was a dragon. Really, the details are terribly fuzzy, as it's been probably 8 to 10 years since I've played it. I believe in the first level you started in this green grassy area and ended up in a cave sooner or later.
Gah, this is probably horribly vague, but I'm dying to remember what this game was because I loved it. Any help is greatly appreciated.
