I really love this game too. If anyone wants to take over from here we would certainly support it right now its about as far back on the back burner until we get the website updated.
It's basically out of memory is a bit of the issue, we have more space since the recent version of arduino and also we haven't implemented any compression either. The compression would help a lot since most of the data is images or text.
When we can get around to the next Arduboy that will have more memory it's something that could easily be done, so maybe then.
