Topic: Other game which I have created levels for: Enigma
Recently (ish), I uploaded a few levels for another ball-rolling game I play (which people around here might already know about), Enigma. (It's the open-source version of this game.) The Enigma forum has its levels section blocked to guests, so this link might not get you to my topic on it, if you're not a member. I had fun writing the code for these levels, which was a reason I wanted to make levels for this game in the first place. Maybe there could sometime be an entirely separate version of Neverball which involved coding in its level creation process?
Here's the Enigma home page: http://www.nongnu.org/enigma/.
I created my avatar with ANVIL-1000MD (c) and scaled it down with GIMP.
