This is like the original tetris, but the tetrominos come from four directions instead of one! The goal is to form full rows or columns which will be cleared out then. You will understand what a "full" row/column is, when you play.
A cleared line gives points, clearing out more than one line at once and clearing lines in combos will give bonus points.
Actually this were only for keyboard controls and I then wrote controls for the mouse to be playable as an Android app, but somehow it does not work as it should. It is very laggy as an app.
I just throwed the code for keyboard and mouse together to upload it here. Hopefully you can use both without any issues, I did not find any yet.

Controls:

Either keyboard:
arrows keys = two to move up/down or right/left and the other two to rotate clockwise/counterclockwise
space = speed up falling
d = drop the tetromino

Or mouse:
Press the mouse and drag it to the side, to move the tetromino to the side. Drag the mouse in the direction where the tetromino comes from will speed up the falling ( = pressing space), a drag to the other side will drop the tetromino ( = pressing d). Clicking on the screen will result in a clockwise or counterclockwise rotation depends on where you click and where the tetromino comes from.

This is just a small game without much action. Since I am not able to turn it into an app, I am not as excited as before to make this game as great as it should. (With graphics and so on.)
I still like my idea with the four sides. I did not see it anywhere else yet, so I want to share it with you.

Too much text, have fun with the game!
