Brick Classic

Only use the arrow keys and rotate to control the blocks S, L, O, T, Z, I, J, so that they fill horizontal rows.
All blocks have the ability to eliminate 1 or 2 rows. Particularly, the block L, J, I can eliminate 3 rows. Only blocks I can eliminate 4 rows.
When a certain number of lines are cleared, the game enters a new level.
The more row you can eliminate, the faster the brock falls. The game ends when the blocks stacked up to the top and don't have any new blocks can fall down
Have a fun!
