While this is a picross game, it's not a very good one. For starters, you can't drag the mouse to mark multiple pieces at once, so you take much longer to solve puzzles. Second, you are not able to mark spaces as "Not Fillable", so it can make it more confusing for the players who need that feature in order to tell themselves where they can or cannot fill in a space. Thirdly, you cannot tell which puzzles you have or have not finished. This can be very confusing for completionists. Finally, I feel like there is no use for the multiple colors in the bottom. Unless you were able to use them to, again, mark spaces as not fillable, then I feel that there is no point to the multiple colors.
Overall, this game has potential, and a good concept and attempt for a picross game. However, I feel it is executed sloppily, and could be done much better.
Things to improve:
• Allow for multi-block selection
• Allow for use of markers to show what blocks cannot be filled
• Show which puzzles have been completed
• Remove colors/Allow for colors to be used to mark different squared as not fillable, possibly fillable, etc.
