Boss Battle: Dr. Robotnik's Energy Suction Machine

This Mini-Boss must be tricked into destroying itself. When the drill detaches from the blade, it moves around and destroys the floor, so avoid falling off. To damage it, hit the blade to open and extend it. You score a hit when the drill attempts to re-attach. Watch out for energy that appears around the machine; touching it will cause damage.

Tips
  • End the Mini-Boss Battle as quickly as possible to avoid falling off the destructible floor.
  • Be careful of the energy that appears around the machine at different times.
  • To get under the difficult rotating drum in Act 2, press Up and Down rapidly as it moves up and down. Jump down immediately when the gap is sufficient.
