One of the issues I ran into with the game was finding freely available art assets. I was able to get a few things from SpriteLib and OpenGameArt.org, and a few more by starting with CC licensed photos on flickr and modifying the heck out of them, but one of the items I had an especially difficult time getting was a simple, top-down walking animation sprite. I did find one that I was comfortable using during development, but I got no response from the creator when I contacted them about official licensing / permission. So, I recently buckled down and hacked together my own 8-frame, top-down walking image series
which I’m releasing under the Creative Commons license (attribution required, derivs OK, commercial use OK) in case anyone else out there has run into a similar difficulty. It’s far from perfect, but it’s good enough to get the job done if you’re working under extreme budget and time-frame limitations.
