Reiner’s Tileset

Well, I’m a hobby game developer. And when i started to make games some years ago, i couldn’t find the grapics i was looking for. So i started to make my own graphics. And the deal is since years: i make games, and i share its graphics with the world then. For free. That’s where this page here comes in handy.

SpriteLib

SpriteLib is a collection of static and animated graphic objects (also commonly known as sprites) that I created between 1992 and 2002 for my own game projects. Seeing how it could benefit others, I decided to offer it to hobbyist game developers to use in their creations free of charge.
