This was cute! Very simple and easy to understand, which can be a big plus for game jam games.
After a couple of attempts where I died quite fast, I seemed to win just by spinning the mouse around really fast. I'm not quite sure if it was the intended strategy, but it may have trivialized looking for the roaches a bit. It could be good to have the loss not be immediate upon a roach making it to the cookie and instead have a health bar that depletes or something like that. It could help provide stakes without immediately ending the run.
Cool game!
