From LEMICO Soft:
This game features a unique gameplay included 63 different levels. In the game you will collect the image using the shape (similar to that used in tetris), which are limited to moving only one axis. Playing in Quadraticus you will be a serious mental work and you spend a lot of time trying to collect a puzzle.
To pass each stage you need to reconstruct the given puzzle image using the provided pieces. You can always see the image using HINT.
Each piece can only move vertically or horizontally, and this is shown in the upper left and right squares of the board while you are touching a piece.
The board can be rotated by using the buttons in the lower left and right or with the accelerometer.
