This is a terrible excuse for Picross. Logic should be the only factor, not guesswork. Especially when you only allow a limited number of mistakes. 1/5
The art is pretty, but the gameplay could use some work. For starters, there's no way to tell ahead of time that you're going into a "moving" path, which leads to a lot of fails.
Den Remodeling depends on which campaign you chose. If you chose the first campaign, you need to get to level 10 or so and defeat the boss there. If the second campaign, collect 9 glowing shards, use them to get a Journeyman's stone, then use THAT to fight the boss.
