This time we are controlling an (apparently) innocent robot which is, in fact, the proud owner of a red laser beam.
Press and hold the "Space" key to activate the laser beam. Hit the red switch to open the vertical gate
You will also encounter several platforms in the level. They weren't built for lazy boys, so be sure to control your sphere while riding them.
Those red spikes are deadly, but fortunately you can destroy the green platform...
...and have a box fall from above and fill the gap.
You will also discover a few elevators.
Things can get quite tricky with several platforms, so be careful!
In the end, you'll have to synchronize the two platforms to get to the other side of the spiky area.
The code is very well commented, as always.
