I have a soft spot for Tetris so I enjoyed this game, however it's very challenging to predict where your block will end up. A projection on the ground would really help in my opinion. Also I didn't get that you can turn the camera with the mouse either as I had each hand on my keyboard already.
Also if you tick the Windows/Mac boxes when you upload the game on Itch it allows players to install the game with the Itch desktop app. It's quite handy and it let people play without all the firewall warnings.
