Has optional english voice acting, and is a really great game in general. Starts a bit slow with some world building and exploring, but you'll soon meet the main characters. And things take off from there.
I highly recommend it. It was also a featured game on RPGmaker.net.
The guy who made this is trying to make additional games in this world, but there aren't many people paying attention to his work... If you play it, join the forum and tell him what you thought! He certainly would love to hear it. (The game does not complete the story... this is Act 1. Lots of content though. Tell him, Admiral Styles, if you want to see more!)
Notes: Uses RPGmaker 2000 or 2003? If you want to improve the midi music I recommend getting Virtual MIDI Synth and some sound fonts...
