I just tried this out. So far it feels very much like Mega Man Battle Network as a more... I hesitate to say typical sci-fi JRPG but that's the closest I can describe it as. Everything so far is well done. I had a laugh at some of the things in the BBS, I was swiftly hooked by the first encounter, and the music and graphics are very nice. I was (eventually) able to find all the items for the item quest but the puzzles and everything so far are very good. The swifter movement with the jet flight helped. My only problem is that there's no way to grind a bit in the shadow dimension before the boss. Definitely looking forward to the full release though. Good luck with development!
Edit: I didn't know of the hidden mob spawn area but through determination and spite I almost managed to kill the boss anyway.
