Oooh nice, I think my next project (tonight) will probably be a game on canvas although it might be laggy as hell. Plus sunslayer Firefox has a console. But yeah Ive made a few ammendments the log shouldnt have even been in there but I commented it out incase I need to debug somthing quickly :P
I also changed the delete keyword thing, I use getters and setters usually so thats why I made it in to a function. But yeah its not needed so I changed it ^^
Thanks for the comments :)
