Krendil presents ...



As the pilot of an asteroid-pushing space tugboat, you must use your gravity field generators to destroy the incoming alien ships.
Use gravity and antigravity to fling rocks at aliens, or make them crash into eachother. Be careful to avoid being hit by a rock or by the aliens' lasers.

Now with survival mode: see how long you can last with gravity always on.

Up - move forward
Left/Right - turn
Z - activate gravity generator
X - activate antigravity generator

Rocks block laser
You can sometimes suck aliens into your boosters and escape unharmed

Added menu. You can now set how many rocks and aliens there will be, along with a random setting.
Is also submitted to Codepoint

Aliens can now be destroyed by laser, and no longer misfire

Set default speed to 45
You are told whether you win or lose in normal mode

Maybe there should be a delay from when you start the game till the aliens start firing. Sometime I'm placed right next to an alien, and don't have time to move before it shoots me.


i like the bouncing effects !
