This one is great. I really love the goal of making things big and chaotic while keeping the sides balanced. The asymmetric upgrade tickets were a cool mechanic, forced you to make interesting decisions.
I found the upgrade selection UI a bit weird. When it opens there's no indication of which ticket is selected and if you press space at that point it seems to just choose a random one. One time I had it get into some kind of buggy state where moving from one ticket to another would cause it to play the tear animation and vanish but it wasn't actually chosen. When I finally did select one, the other two reappeared briefly and then vanished for good.
It felt like it was very easy to get things permanently out of balance by growing the size of one side. Basically the only way to recover from that was to increase the population of the other side. I only managed to get my multiplier above 2 one time.
