Radar Avoid
Just messing around with some very basic maths and simple VB concepts.
Basically there is a circle, it moves about and bounces off the walls. Very pong-like.
Your mouse has a radar-like field around it, hence the game name. You can grow/shrink the field by right clicking and dragging up/down.
The little circle is repelled by the field.
That's the "game"!
Kinda fun if you have the sadistic urge to chase a little green circle about :)
