It took me a little while to figure out how it works, but I found the idea interesting. I’d suggest including some kind of tutorial or smaller introductory stages.
In game jams, you usually need a way for players to quickly understand your game. There are so many games to play and rate, so I recommend adding ways for players to learn how to play yours.
I really like strategy games, which kept me engaged a bit longer, but I agree with the others that it was a bit heavy for a game jam.
