Very nice that you could make a game with your kids - and congrats to them, this is a very good jam game!
It is pretty fast to clear once you figure out the jump back mechanic, which is actually fine for a game that people will play a few minutes anyway. My main friction was the energy depleting very fast, even late in the game. This makes the jump mechanic even more central - so if I was to give feedback, I’d make the “Jump to station” icon stand out more. Maybe animate it when the bar is full, with a “press T / J” message over it, and I’d put it closer to the things the player looks at - the energy and the health bars. Perhaps even adding a short popup message over the ship, like “Alright, ready to jump!”.
Oh, and I loved the space ads!
