N00b here. I bungled my code so badly on the Shield Rush (forgot a set of parentheses), that not only did I get an “Aw, Snap!” in my Chrome browser, but I can’t re-open the level in order to reset the code, as every time I try, Chrome gets the same error. Has anyone else had this problem? How do I fix it? I can’t progress any further until I’m able to retry this level.
