Just a quick update - I've made the jump to my new development machine and had some teething issues regarding some of the shaders not behaving as expected. I've put a stop-gap measure in place to handle it for now, however it's meant that the next release will be delayed by about a week. The good news however is that the new machine is considerably faster than my old machine, which should help speed along future releases.
The additional tools that I've built are helping speed up development in a big way, and as such I'm trying to take advantage of the time gained to add in some of the suggestions from the recent poll. I could have simply offset these gains against the time that I lost migrating to the new development machine, however this will be the final chapter for Yui, and so wanted to add in some more content before moving on to the next character.
Thanks again y'all :)
