The game mechanics were easy enough to figure out, no thanks to your so-called tutorial. A tutorial level's supposed to introduce new players to the game basics so they know they're supposed to be sliding squares around the main grid until all the pieces under the purple things match the square at the bottom of the column on the far left. You should also make the Standard Mission numbering a little less confusing--number them 01-30 or 00-29 or more clearly differentiate between the three groups of mission that are apparently indicated by using 01-10 three times. The achievements aren't anywhere near compelling enough to make up for the generally uninteresting gameplay, either.
On the plus side, the graphics are nice and I appreciate the mute buttons.
