Im gonna have aliens mutate when two adults meet
circle->quad->octagon->dodecagon
also Im thinking the humanoids down the bottom 'are your lives' thus protect at all cost, they can mate + produce offspring, but youre not gonna run around doing the stargate strategy of shooting all your humanoids except one to make the game easier
btw - Im looking for some suitable freeware aracade space sounds
does anyone know of any?
