Ferd, your logic is bad. You didn't prove that I won't think of using my keyboard. If I do not think of using my keyboard, then I will fail at this game. I might think of using my keyboard. Therefore, you cannot prove I will fail at this game.
To get "It's ROB!" You need to fly directly upwards. Don't fly at an angle, fly perpendicular from the ground. You will have your fuel refilled. This only works once.
To get "Rise!" You need to fall while facing directly downwards. Look for the angle with highest resistance and just fall. You will be shot forward. Again, only works once.
Both of these seem a little luck based, but you should be able to get them within a few tries.
@UeberBob: If you send out tentacles, it drains the power of the cell depending on how long the tentacle is. If there isn't enough power for the tentacle to reach, the tentacle will retract, and return the power back to the cell. Something like that happening?
@sometimestommy: First time I saw this game, I figured it was Zach with a different account. This game is not at all from Zachtronics Industries. The creator even goes as far to say that Zach was an "Inspiration" for this game.
