Nice mix of theme and classic Tetris!

Played this on stream. Check out the vod here for my thoughts. https://www.twitch.tv/videos/1005231236?t=00h13m28s

It took me a bit to understand, what was going on, but then I was hooked.

Great job!

Fun puzzle game. Was quite challenging to keep on top of both sides.

Nice work

I enjoyed this! Fun to balance what will help each side. In the first couple of minutes, I would make the release time slightly slower to give players time to figure out how it's working and get the hang of it. 

Smart twist on Tetris.

I found A and D moving up/down instead of the expected left/right not very intuitive to control the game. I'd suggest either rotating the playground 90 deg to be vertical, or use W and S for up/down in the current layout, so key strokes matches the visual direction of the cursor motions.
