Oh, have I ever been testing! ;-) Reminds me... I need to email a crash log. And post a few bug reports.
I really like the changes in v0.15.2. The new voice that comes up while docking, or when you run out of energy, is pretty cool. The UI revamp is awesome, and seems to be much more readable at lower resolutions. If I'm not mistaken, it also seems like the music has been revamped. I don't recall that lovely vocal part being in previous versions. On that note, I would like to commend whoever is doing your music and sound design. They are doing a fantastic job, and I cannot wait to get the soundtrack to the game once it is available.
