Thanks! We're glad you like the game.
The screensaver is intentionally really simple. We've talked about adding user-controlled settings, but the basic idea was just to make a free download that gives people a taste of the Kaloki universe and encourages them to come to NinjaBee.com. Since we don't earn any money off the screensaver, we didn't want to sink too much time into it. Still, we'll consider doing an updated release in the future and adding user-controlled settings.
Yeah, sound is intentionally off - we think it's annoying for a screensaver to start making noise whenever it turns itself on, but that's just our point of view. Of course, another optional setting for that woule be nice...
Thanks for the feedback,
