Thank you for your feedback and for giving us things to think about!
I think in the state the game is, without all the necessary tweaking, might feel a little boring. But I don't think it's potential as it's doesn't have depth. You have to manage your batteries, you need to aim carefully where you impulse your ship, you need to take time to recharge but you also have the supernova to take care of...
But I agree that you currently don't really feel that since there are some bugs and our level design isn't great right now ><
