Hi, thanks for playing. If I agree with that our game could use some balance tweaks, I'd disagree on unlimited impulses as it would remove some strategy, some depth.
With limited charges, you have to orbit a planet to charge, slowing you down, loosing some time for the nova to catch up. It serves the gameplay, the art and the narrative. For me it's a core mechanic we shouldn't touch too much.
More planning, less spamming.
