Geo is a simple, experimental game that uses a type of genetic programming to grow enemies to shoot at (and that shoot at you).
Your job is to collect all the gravitational energy units to progress to the next level. Your enemies (the geo entities) develop by passing the code used to describe their form on to offspring, which are spawned once they gain enough energy. This code is mutated slightly each time, meaning that a kind of evolution can take place. The path of this development is partially governed by your actions, but generally, geo entities emerge that populate space dangerously quickly. You will need to find ways to control their numbers for you to complete your mission.
Due to the nature of random selection at the start of the first level (the initial enemy entities are entirely randomly created), games can be quite variable in terms of difficulty.
Everything in this game is created procedurally, from the geo's forms to the sound effects.
InstructionsThere is no mouse control, use cursor keys to play the game, and to use the menu system. More details can be found in the information section on the game menu.
Controlling your ship:
cursor up: Thrust forward
cursor left/right: rotate ship
cursor down: braking thruster
space: fire weapon
number keys: pick weapons, they will be enabled as you collect them.
f: fullscreen mode
w: windowed mode
p: pause/unpause
q: quit game
Hint: Some of the harmless geo entities are quite harmless and are useful as an energy source if you land on them.
The green dots in the backgound comprise your scanner. Small dots are geo entities, larger dots represent gravitational energy items that you have to collect. Collect the star shaped pickups to increase your weapon arsenal.
The energy items and weapon pickups will orbit chaotically around the geo colonies. Some are faster moving than others, you will have to develop your flying skills to collect them.
When you fly near enough to the energy items, they will switch to following your ship. As well as allowing you to leave the level when you have collected them all, the energy items have another use. If you fly too close to the geo's defensive modules they will fire homing missiles at your ship. The captured energy items in your possesion will shield you from these attacks.
