Asterope Is surprisingly fun, you use your grappling hook to grab onto asteroids to move through the game. The longer you remained attach with the hook the greater the turning angle. It's a nice take on game navigation. It's short though, just 10 missions, but it has arcade modes. Hopefully the dev will add more with updates. Overall it's only $3.99, it's fun, but with the recent trend, you can wait and they might bring the price down.
