Algodoo

A third type of fruitilizer that doesn't cancel out all movement. Depending on the Fruitilizer's orientation, it either goes up or down as if it's on a rail. How it is, if you just start up the Fruitilizer (Enter), It will want to go to the right or left.

If you, say, place the rocket up in the air, with no speed in any direction with the Fruitilizer on, the rocket will move down very slowly, but be able to go to the left or right at any speed you want. If you turn to Fruitilizer 90 degrees, the rocket will go up and down easily, but it'll be very hard for it to go right or left.

Controls:

Up/down - turn
Right - rocket thrust
Enter - Fruitilizer activation/de-activation
