Javascript Sim City

I have GPL licensed Sim City clone written in Javascript. It has some problems which has to be rectified/modified for us to use it. 1. It doesn't run in IE because it uses "canvas" which is not supported by IE. 2. Save function is not working properly. the game should be saved in the hosting server "mysql" with the userid. 3. More than one should be able to play at the same time from different browsers over internet. 3. Optimizing the speed of the script. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased. (No 3rd party components unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the worker's Worker Legal Agreement). ## Platform Browser based and should run with all.
