Apart from fixing bugs, do you plan new content? I recently reached round 500 because once you get to 60 every single round is exactly the same and I scale faster than enemies do so I just got an autoclicker clicking the first upgrade and I got into the point where I barely saw enemies. It was fun to see the fire with every single upgrade but it lost the meaning knowing I've been fighting the same enemies for over 400 rounds. It's fun.
