Please add a character that you unlock with the Konami Code to unlock. (if you don't know what that is look it up). anyway if you can't take a and b as input hen you could do left and right click
If you add ascension/reset I'm guessing its something like you "ascend" by selling all the stuff from your current ship, to get a new ship in the world that has more gun slots, or cheaper to upgrade?
It would be cool if you could make things move, so you can store heat in coolent cells, while a heat exchanger moves from left to right, to take it out of one and out of the other, and moves to put it in a third thing. something like a robotic arm
I have multiple ideas but don't want to spoil them all, i've posted some in other comments :) Now it's time to select best and combine.
