"I'm liking this, but the content seems to be gated way too heavily by star accumulation..."
but it generates a great feeling of constant progression.
exactly that pulled me in. "i will come back with a better ship and take my revenge!"
and now i'm already closing in to complete the race to the perfect ship.
i had bought the star doubler and ads removal, and did not regret a single cent.
yes, the game is more like a premium game with free to play trial/demo content.
from stage 3 (insane) onwards you can earn up to 3000 stars for a decent run.
so you will always make some progress.
now it's time to replay all levels (again) for pushing up the highscores.
just got a new co pilot who is very promising for achieving better results.
game has great staying power and great replay value.
and the devs have announced more new levels and content.
