Nice entry!! The idea is clear and simple, but you executed it greatly. The game art and the music are really solid, and the controls work smoothly - in their own way :P
However, I'm not really good at Tetris, and this one... was a hell for me :/ I felt like I lost any control, and the game was just responding randomly to my keys, and I wasn't able to understand which glitches were active and how to deal with them. Again, I suck at the original game, so my words are not statistically relevant, but just be aware that your game is pretty hard :)
Thanks a lot for your submission, and congratulations for your first Godot Wild Jam! :D
