It's a pretty good game, with nice atmosphere and movement. My only complaint is the timer runs out too fast, I can't even go to where I want to go or know whether I went to the right way. The voice acting was a nice addition too.
Oh yeah, another bad thing is I can't immediately tell which wall I can bomb since the tile gets dark just 2 tiles ahead of me, so I really need to be right in front of the bombable tile to tell.
