''– Rotate the character 90 degrees to the left or right by pressing a given key'' <br/>
''– Change the stage background. '' <br/>
'''We ask the following question:''' What do we have to learn? <br/>
''– How to recognise that the character has walked into a wall, i.e. a prohibited stage area, or reached the exit <br/>
– How to move the character backwards, i.e. reverse it <br/>
– How to play sounds (unless we have introduced this command earlier in class or as homework / an additional task).'' <br/>
