TETRAMINO

I found a bug

The ghost block sometimes wouldn't fall when a line(s) would be clear

Rarely a piece would get pushed inside another or be pushed out of bounds

To further add onto the grid bug, I have seen it happen towards the top of the grid when it starts to drop faster. Guess it could be related to the drop speed? Apart from that, as a tetris fan myself, great job.

Found a bug where the tetramino doesn't align with the grid.

Sometime when you turn the block near the edge, the block goes outside the border.

The time goes on when you are in the menü
