Sorry, I didn't get how to change the about text, so I give credit here:
Most textures were made by Lanea Zimmerman (Sharm)
The bald man was made by Cough-E (find him on opengameart.org)
The music was made by:
Soliloquy: Mathew Pablo (opengameart.org)
Medieval: Miguel Herrero (opengameart.org)
Mysterious Ambience (song 21): cynicmusic (see: pixelsphere.org) but got it on opengameart.org too.
That's all. If anyone needs more credit, just comment here.
