I found a problem with level 2, puzzle 5: there are multiple valid solutions for the pattern as it's laid out, specifically as refers to the bottom of the man's face. You can tell from context what the expected solution is, but I originally had all requirements met with a different solution than was accepted.
I found this incredibly entertaining. This is gold. Keep up the great work.
Not the best picross game I have played for user friendly play, but it was nice to have the levels in color.
I love Picross games !
Adding the colour makes it more challenging, it feels "refreshing" =)
Although, I agree with the other reviewers, you should add a calm music !
I would also suggest you to allow players to add the possibility to press a key (like "x" or something) in order to mark the blank squares, 'cause having to click all the time is a bit annoying.
I still give you 4 stars, (I would have given a 9/10) and note you 5 !
Even though the game plays well and looks clean, I don't think there was enough done to make the experience very engaging. Adding a high scores table, user-made levels, unlockable medals, and (like others have said) sounds and music would make the game more addicting to play.
Because of the private way this game is set up, there isn't much more for a user to do than play through a few puzzles and just MAYBE look at the Conceptis website for more information on the game.
