This is a perfectly functional puzzle game with time attack and maker modes. I had a lot of trouble with these; I did a lot of random clicking until I discovered some tricks to methodically solve some formations. I was having fun. Then I started randomly clicking again when I ran out of tricks and was faced with these two-column formations in the last four puzzles that messed me up, and I really hated it.

I shouldn't let the sour aftertaste of the difficulty get me down that badly, because the puzzles are fine as is, but the sound and visuals are ass, so this game really doesn't have a lot going for it. Go look for something more substantial, and make better life choices than I did staring at these puzzles for hours on end.
