Well a few things.
There have been several complaints on the randomness in the queue of this game. Honestly I have no problem with it, I think this game is based on how to sort your necessities at a moments notice. Quick thinking is the point of it.
Its not worth mentioning the graphics and style, both are obviously well done.
The main thing that irks me is the monsters shown in the queue. I feel slightly uncomfortable that I don't know what kind of monster is coming up since the monster icon is the same for every one.
I still stick to liking the random draw of shops and enemies but I also suggest a progress bar to the boss. That would be the only predictable thing I'd want for this game.
