The equation f(z)=acot(z), in the form of a colour map, cuts off from -i to i, but otherwise the colours are joined together. I named this level after the equation because of how the level is separated from the centre where the exit is located.

Possibly the hardest one here. This level is based on Colony, but the techniques to solving this level is very different. Here, the toggle doors are completely randomised, and the tanks partially. You might find it helpful to find a pattern in the tanks' movements. But watch out for fake popup walls, they might hit you any moment.

Based on the CCLP1 level. Like the original one, remember that this is NOT A MAZE, and you can see there's a pattern in the hidden traps: it's also in the fake walls. But watch out for where the pattern breaks,... oh, bugger, I guess it is a maze, but an easy one nonetheless if you know where you're going.

The "hidden cameras" here are the teeth. It might seem impossible at first, but there are teeth hidden from view that you can trick into opening the "security system". The solution is somewhat similar to that of "Totally Unfair". But watch out for green buttons, and make sure you walk over them an even number of times.
