Really neat game. Very impressive to see something so nicely fleshed out.
The airship destruction was very satisfying and the game as a whole just felt very polished. (I especially liked the way launching rockets felt.) As far as feedback goes I do not have much, the game looked and played really well. Perhaps some music would have been nice, but honestly this is a game jam and what you have here is damn impressive and polished.
Well done, and thank you for sharing your game.
