There's some pretty significant input lag that makes rotating and placing blocks a pain. Other than that, it's an interesting concept in theory, but basically all you've done is remove the difficulty from Tetris. If it weren't for the aforementioned lag, it would be very simple. Otherwise, it is good.

I had fun playing this game! feels polished and plays well.

Aside for the input lag as mentioned before, I blame the web player though.

Congrats on the entry!

I feel the idea works pretty well. Love it. Good Job!
