The tileset used in game was modified from a sample tileset found here.

Spriters Resource - http://www.spriters-resource.com/
Didn't directly use any of these assets, but the various animations in the spritesheets of classic games were big inspiration.

Tools:

Audacity - http://audacity.sourceforge.net
Audacity is an open source sound editing suite.  It can be used to record and edit sound, and export to WAV or MP3.  I used this to record various sound effects, change the pitch or length of others, and noise.

Gimp - http://www.gimp.org/
Open source Photoshop.  Used to edit pretty much all visual assets in the game, from the sprites, in-game objects, HUD and background art.  The two biggest features are the ability to work with the Alpha (transparent) layer, and split images into Grids (which is essential for lining up textures in spritesheets / animations)

Camstudio - http://camstudio.org/
Similar to FRAPs, used to record video for playtests and trailer.
