Quite the rip-off of picross DS.
The same color scheme, except for the ugly offputting orange background.
Similar fonts for the puzzles, timer, and level selection screens.
Heck, virtually the same layout of the puzzle, timer and level selection screens.
The only thing different aside from the ability to number the squares is the lack of animated colored completed puzzles and themes.
Oh and the horrid interface clash of the different buttons and main screen (i guess the author tries to be a bit original here, but it just clashes with the crisp graphics that were copied).
too easy, no strategy involved, if you actually want to use some strategy its a bit hard
selecting overlapping units is problematic, often i missile a troop instead of a missile launcher
antiair missiles would be more useful if they autolock on targets. if it takes 2 seconds for the plane to hit your tank, and 1.5 seconds for the missile to hit the plane, it leaves 500ms for you to prepare the missile and click on a rather fast moving target.
spam artillery once it's available and game becomes trivial
