game development

seeking an experienced game developer that may be able to handle specific tasks to be paid for - not based on hourly but by accomplishment for task upon negotiated price. Summary of first task is to properly implement ellipsoid collision detection and sliding response

It's called Megazeux. It's not that hard to make games with it.
The problem is that it is not internet-friendly.

Also what the hell is a " ellipsoid collision detection and sliding response "? Are you talking about a oval hit-box with a diagonal correction if the character is walking in place against a wall so that they are still in motion but at a angle instead?
