Pretty interesting concept, with a nice execution. Plus, I really enjoy more slow-paced games that challenge my brain. The music fits nicely, too.
The main negative I have is some glitching. Along with the character's movement switching between lagging and jumping, I ran into a glitch several times where I suddenly disappeared and reappeared on an entirely different spot on the map. The second time, I actually ended up outside of the entire dungeon! A very minor fault is that some of the wording is incorrect and a little confusing, at least on the English version.
