Collapse (UK) (1985) - Amstrad CPC - Puzzle, Strategy

Collapse is a simple puzzle game where players control Zen the Mole who is presented with a network of sticks that he must turn blue. Zen does this by simply walking over them while he is yellow. To get to the network, he must turn himself red so that he can build bridges that lead to it. Zen's redness disappears after a few seconds and he turns back to his default state. Once Zen has managed to turn the sticks blue, he can unleash the Rotox, a white line that moves around adjacent blue sticks, destroying them once the Rotox makes contact. When all the sticks have been destroyed, Zen proceeds to the next screen.
