Another development secret is here.
In the bottom right corner of the level (which can be seen in the fifth screen shot), there are a bunch of scrapped robot laying in a corner. Most of those robot's where based of concept art for Algorithm Joe (by this point in development, I was gonna use normal Joe is mode 1, but then decided, that Remote Joe would fit better, which led me to think of concepts for another robot, one based on following an algorithm), except for the blue one with purple eyes, that used to be Remote Joe's sprite.
