There's a need for free graphics to use in various projects. However, you can hardly ever find anything useful on the net, and game authors rarely have enough time and skill to make good graphics by them selves. That's why free games have usually pretty poor graphics, and most of the time not animated. I decided I'll try and make some sprites to be used freely in your games. You don't even have to mention my name, although I'd be glad if you did. You can also modify those pictures, and generally do whatever you want with them – I put them in public domain.

Here are some construction kits – you can use them to make the graphics you need for your game.
Just play with enabling and disabling the layers of the construction kit image. Some combinations of layers might require additional corrections to look good. Once you've got the combination you want, just flatten the image and save it as the format you need to import it in your game.
