* Shoot water bullets on land, after being in the water.
* Shoot air bullets in the water, after being on land.
* Land and air robots cannot become wet. You can destroy them with water.
* Underwater robots cannot leave the water. You can destroy them with air.
* You regain a health point with either 10 gems or 1 large gem.
* Strategically sacrifice a health point to save a bullet for later, then refuel with gems as soon as possible.
* Strategically ration your bullets, and plan where to refuel air or water.
* If you lose all your health points, you automatically teleport back to the start of the level, without losing progress.
* You have infinite lives, but your number of attempts is incremented each time you restart a level, automatically or manually.
* You can manually teleport to the start of a level without losing progress. This is useful when you dont want to backtrack from a dead end, or just as a fun way to escape the robots.
