Cave Game Need Section Recoded! $400

I have a simple side scrolling cave game with obstacles. The algorithm that creates the cave works fine, but sometimes the obstacles combined with the cave location make it impossible for the character to pass through.

This should only need a quick patched addition of smart code, but even if it took total rewrite of the algortithm, it’s very simple stuff so $400 should do the trick.

If everything goes well, I may want to keep you on board for future work.

I would appreciate any work examples.
