Hey! That's an interesting thought. I guess yeah score only gives you a funny pun rank at the end of the game. IF multiplayer would I dunno improve damage or accuracy - yeah that would've been so much better. Thanks for the suggestion!
Well new enemies are harder to code/add than just increase accuracy/damage :D But yeah, I agree, it lacks a bit of content, it would've been nicer if it had some rocket guys or a sand worm. <3
