Description

This is a remake of a game I made and lost (didn't back it up) a few years ago. You are an electron with a -e charge and you have to maneuver yourself around the "course" until you reach the atom that is missing an electron (+e charge). You are propelled by an electromagnetic impulse and cannot move again until you come to a complete stop (the gun that provides the electromagnetic pulse isn't accurate or fast enough to act on a moving charge). Your world is populated by other charged bodies whose magnitude of charge is directly proportional to its radius and whose charge is indicated by color: red = positive charge and blue = negative charge. In layman's terms, you are attracted to red bodies and repelled by blue bodies and the bigger the body, the more you are attracted/repelled.

I am a supporter of the Open Source Movement, but I am even bigger supporter of competition, so code will be released at the end of the contest.

Tips:
- Although smaller bodies have less charge, it is more difficult to escape their surfaces.
- It is often better if you go from one body to the next instead of going for a hole in one.
- Don't panic on hole 18. Also, it might help if you don't use full power.

Instructions

Camera Movement:
W/UP = UP
A/LEFT = LEFT
S/DOWN = DOWN
D/RIGHT = RIGHT

Ball Movement:
Click and drag to set the power. Release to shoot the electron.
SPACE = RESET BALL (does not restart level; used in the event of a wild shot that is orbiting or reached terminal velocity, etc.)

Goal:
The goal is to get the small white ball (the electron) into the hole (the yellow, positively charged atom).

Bug Fixes:
- The game no longer eats your CPU
- Added support for moving with UP, DOWN, LEFT, RIGHT as opposed to just WASD

Great game. Source code doesn\'t display for me :(

Thanks. I set the source code to display once the contest is over.

I meant to note this earlier, but my high score is 1 under par

Fun game but, 1) space bar doesn\'t seem to do anything. 2) on a wild shot, the ball just drifts out into space, takes a loooooong time for the game to reset.

That\'s what the space bar is for: to reset the ball \"in the event of orbiting or reaching terminal velocity, etc.\" If you take a wild shot, press space to reset the ball so you don\'t have to wait.

Scratch that, 7 under par

I guess I wasn't clear. When I press the space bar, nothing happens. The ball just keeps drifting off. I keep hitting the space bar, nothing happens. Eventually, after about 45 seconds, it resets.

Ah, I get you. Does WASD work for you, or are those messed up as well?

I just re-did my I/O, so hopefully it will work for everyone :D

18 under par!

Sweet, now I'll spend hours playing! Yes, your I/O change works, camera keys work and space bar works. Cool game, it's very addictive.
