Today's #devlog sees me losing a fair bit of steam, chasing my tail on code performance issues.

I've also been reading a bit about #jruby - maybe I'd get some speed boost from that, but I should focus on the core issues at the moment, I feel. But, I would love to make use of concurrent threads. They'd be very useful for this game. I hear this is coming to MRI, but probably not soon?

I forgot to mention that in the video I'm showing a diff (with git difftool); left is before, right is after.
