Picked this up yesterday since I really enjoyed the Etrian Odyssey games. I put around 2 hours into it today and have some impressions for anyone interested:
1- super minimal story (literally told to go get back something important stolen by an evil wizard)
2- super minimal graphics: either pre-8bit wireframe graphics or stylish hand drawn graphics, either way they're even more basic than the ones found in Etrian Odyssey.
3- gameplay: solid. if you're into leveling up characters, or grinding, this is right up your alley. the game is also quite tough, and very unforgiving.
Overall a good game if youre into first person dungeon crawlers. I still like EO a little more than it, but that's based on my first impression, things could change. If you like this style of game, it's easily a 9/10, but if you would rather have a JRPG or something that is story based and modern, it's probably a 2/10.
