Thank you for the kind words and helpful comments.
Yeah, AI would have made a lot of difference. Though for a game jam game, I was just happy to finish this much in time. It might be a nice after-jam addition, though.
The planet's movement was tricky, and as you say, it takes a while to stop moving. Each planet has its own mass and drag based on its size, ill look into that as well after the jam.
As for sinking all the planets on your first turn, perhaps an angry message from Player 2 would be a good addition. :p
