Great puzzle game that had lots of clever ways to break symmetry and each mechanic felt unique and synergized well with the other mechanics! The game felt very polished and the difficulty curve ramped up well.
As other's have mentioned, an undo button would be great for the post jam version!
I got stuck in a later level (I think 3 levels after introducing kill) but I plan to go back to it and finish the game. The final screenshot looks like a monstrous level :)
