DOS Games Discussion

When I was younger I would travel to my grandparents home and they had one of those cd disk roms with 1000 games and there was always this one I loved to play. It was a 2D platformer in this weird and colorful world, the main character was kind of just a normal guy with blue jeans and a t-shirt. I don't think there was combat per say maybe just like Mario style where you jump on enemies heads, I do remember an enemy that was literally a floating eye ball that would just bounce around and try to hit you. I really feel like the game was named Roy and there was like 2 or 3 sequels but I can't find them for the life of me. Please help, thanks!

Not one of Commander Keen games?

There's also a much more obscure game called Rodge Rock in Retroactive but it does have combat. The main character wears jeans though. I don't think there were any sequels.
