Loved the intro! Super funny! Great game with a great art style! A few things I noted, intended to be helpful for you, is as follows:
1) The planets coming to a stop took a long time, so I was waiting for a while to take my next shot
2) I was able to sink all the planets on my first turn without letting the other player take a turn
3) It is a bummer that is is a two player game, I thought you had an AI setup for the second player, so I played again to see how it was and was disappointed it was not something in the game - I don't blame you, that can be hard to figure out!
Cool quick game, good job making this!
