I really like the implementation of the theme, especially because I struggled with it quite a bit and its nice to see others pulling it of a lot better.
Altough the interpretation of the theme ("You swap roles with the computer that is processing the players inputs") is probably something common in this jam, I like how you executed it here because the inputs of the player become actual gameplay elements in a tetris level.
The game is quite hard (at least for me), so its nice that there are multiple patterns you can form, instead of just trying to complete lines.
