It would be really useful to have a page that simply lists all of the levels you have played and lets you click one and see the currently active code for that level. (Without the actual game being there). Sometimes when people ask for help on the forums, etc i go back to my level and look at it to refresh my memory on how i did it.
Kind of sucks to have to go to the level wait for it to load then click play etc .
Just a nice to have!
afterthought, a code repository would be nifty as well. built into the game where you can “save” some code there and reference it later… not tied directly to your active code… that way you can toy with it at will and then just reload it from your repo
