Disapointed ...
Great idea for a good puzzle game ! However:
-This is NOT a puzzle game, in some lvl's u dont even need to change the colors to win ...
-The primary colors are Red, Blue and Yellow. Green is NOT a primary color, it is the addition of blue and yellow. That error made it kinda harder to remember what effect the yellow cross had
-lvls like lvl 22 and 30 are just retarded, make the game boring.
I would recommend you ad a custom lvl maker so users can make their own lvls, cause the idea itself is really nice!
