Aim carefully when moving into small cubes with gaps around them to avoid going too far and falling off. If this happens, you will be forced to restart. If an object in the scene rotates, you can balance on it at different angles while it spins as long as you move carefully. However you will eventually fall off; only use this if it is necessary to turn a corner or reach a stable area. The entire path in front of you does not have to be visible in order to move forward. As long as there is no obstruction in the hidden area, you can tap an accessible block anywhere along the path and your robot will advance to its destination. If you are not sure where you need to go to complete your goal, tap around the blocks to determine which are open. This is indicated by a small splash circle. Areas that are off limits are marked by a red "X". Your robot will move to any place that is open. Before you begin moving through complicated maze-like areas, consider working backwards by imagining the path from the goal to your current location. Red bots always turn 90 degrees to the right. You are safe from zappers as long as you stay one square away.
