Great game! really helps me stay calm in times like this. I do, however, have a few suggestions. maybe you could optimize the infinite levels mode playing experience by having settings for which puzzle parts the player wants. for example, I prefer not to play levels with the two "players" (I don't know how else to put it since this game is so abstract). maybe one could disable that for playing computer-generated levels. another thing I would like to see in the game is a way for you to make your own levels and share them with other players. obviously the "sharing with other players" part wouldn't be easy to implement, so maybe each user generated level could come with a shareable seed. I really like giving feedback on indie games, because I feel a closer connection to the people/person actually behind the programming. I can't exactly just tweet at nintendo for things I want in their games and expect it to actually happen.
Edit: sorry if I got a bit off topic at the end of the comment
