Objective: Make the red traveller cross over as often as possible. How? The mouse guides the blue portal. You have 30 seconds. REMIX CHALLENGE: 1. Coding: Once the traveller is caught 3 x in a row, the speed with which the blue portal follows the mouse increases; once the traveller is missed again, it goes back to that agonising 2 steps. Argh! Hint: Use variables! 2. Graphics. Backgrounds and portal & traveller design.
