Before taking your rocket out into space, learn to control it in the obstacle course which is Gravity Thruster. You'll be flying in a gravitational field, so you have to thrust with one hand and steer with the other. Learn to use the tractor beam to carry orbs along with you, so you can move them to their goals to unlock the exit portal and fly out of each level.

Watch out for blocks and other obstacles, don't hit the floor and beware of the auto-aiming gun turrets. Don't forget you can shoot back at the guns and obstacles you wish to to remove. To unlock the next level, complete the tasks and get your rocket to the portal without incurring too much damage.


The in-game animated instructions will guide you.
The aim of each level is for the player to to fly their craft into the exit portal.

Crates and automatically aiming turrets may block the way and need to be destroyed!

Orb's will need to be picked up by the craft's tractor beam, and placed, dropped or propelled correctly into

position on each empty plinth with the level to activate the exit.


The in-game animated instructions will explain the controls.
Use the Mouse to Direct your craft, mouse button or E to Shoot.
Use Up Arrow, or W to activate your crafts thruster to propel it forwards.
Use Space, or Q to activate and deactivate the tractor beam.

whats the max score on level 14?

The controls were completely bad.

What the controls should have been...
Press A and D to rotate your ship counter-clockwise and clockwise, respectively, with W to activate thrusters. You will need to have a reasonable rate of rotation, not too fast and not too slow.

Press AND HOLD spacebar to use tractor beam, RELEASE spacebar to stop using tractor beam.

Left mouse button can be for firing ONLY, and not for maneuvering the ship! Also you can leave E as an alternate fire button so the mouse wouldn't be need to be used at all.

Still wouldn't have been great controls but would have been a whole lot better than what was chosen.

Clunky game. Slow. I get the concept and that the difficulty of controlling the ship is what makes this interesting and challenging, but I think it's a bit too much. Great music though, as it strongly reminds me of Jazz Jack Rabbit 2. Nostalgia.

The Editor level was a nice touch. The controls were a lil loose though and were a hard to get used to but besides that, the game was very inventive and had an 80s game feel to it which is quite rare in games now days.... All in all a 3.5 game not the best game but definitely not the worst game either. Somewhere in the middle. :)

Great little game. Nice and inventive gameplay. Good work -)

Penry responds:

Thanks - it's bases on a very old dynamic, but we've added a few twists and turn for anyone who knows the games it's based on from the 80's
