This a really cool game mechanic really well executed! I especially liked the dots that you used to signalling the direction to astronauts, as that helped both with navigating the map and lining up slingshots. The asteroid explosions were a great addition too, as using them both increased the challenge and the speed which is a great balance for speed running in my opinion. Overall this is a really well made game that executes a simple, but fun, concept really well. Nice job! :)
