just rating this for xp lol. not that good but good enough

It took me 10 minutes to get 20 points. Kill me.
On further playtime I discovered that you use the spacebar to make it go down.

Arrow keys to move, Q to flip. Stack all the pieces and reach the maximum score!

Could you just map the rotation to the up arrow, and make it so that the down arrow moves the pieces down faster?

I do love me some Tetris! Nice job with the slow movement and the pacing of the blocks. Use of colors is very appealing. Some tweaks I would like to see: utilizing a faster drop, more variety of the blocks, and when possible, I like a preview window showing the next block. Also when I got to the final drop and filled up the screen, my score restarted at zero and I lost my final score. Overall, a nice start to a new Tetris game.
