On to the next task - the background. There is a lot of space to cover and with the level of detail in the character, platforms and the enemies it will need some work and detail to match.
Now that I am done with the step-by-step tutorial and ready to post it here, I realize that I did explain some of this briefly in the tank tutorial a while back. Blame it on my old age or just having written too many of these tutorials to remember properly - but I still hope this is helpful as it's a bit more detailed.
Next up will be a part on creating pipes, connections and some nice silhouettes for the background.
