While I'm not entirely sure how the game fits into the theme this is my first time seeing this kind of game in this jam so good job on the creativity.
The game seems like it could be great fun with some strategy added onto it. I couldn't really understand how can I optimize my playthrough, I just built buildings and upgraded rather arbitrarily maybe if the math of how much money you'd get from each building size / upgrade it would have been easier (at least for me) to get an idea of what I should do or not do.
The Kaijus were very cute!
