Thank you so much for playing the game. You are right about the slow rockets and it being luck more than anything else. The four slots on the bottom were going to be for other weapons, an ice rocket that froze the planets in stasis for 15 seconds. A fire rocket the would be a very large fire ball, and finally a seeking rocket that would be able to track a planet and destroy it. The special rockets would drop RNG from a destroyed planet. I just never got around to it, mores the pity.
Thanks again for playing the game, it is appreciated. Looking forward to next year!!
