I do applaud the wanting to improve performance elsewhere, but still gets a big shake of my head in disappointment that dev is allowed to get to a place where it only works in one browser at first until some amount of work after release to fix to work in other browsers. My sincere hope that you do get it to work universally, realize what was done that made it one-sided to begin with, and avoid those things in any future projects.
I understand the "let's do this for the lulz and see what happens/learns/etc", but once you feel like it is "good enough" that you post it to the public (for let's face it, publicity/showing off/self-promotion), you HAVE to expect that some people might think it isn't good enough and here's some ideas to make it better.
That's not to say that what was posted is shite. It's just with a bit more...it could be even more.
