Amazing, far beyond what I'm used to seeing on sites like this - not only well made, but well designed! Visually reminiscent of early MMOs like Ragnarok Online, great animation, my only real complaints are that it's easy to get lost, some of the terrain feels a little stylistically inconsistent, and the interface looks like something from the early 90's.
Production values: 9/10
Mechanics: 10/10
Narrative: ?/10 (I haven't gotten far enough to comment on narrative, but the comments are encouraging)
Overall: 10/10
Recommendation: 5/5 - a must play!
