The grapple mechanics have a lot of oomph to them they are SO satisfying.
That said, I feel the difficulty ramps up a bit too quickly, after the initial phase of idly collecting the scrap I soon found myself completely overwhelmed by meteors with no time to save up enough scrap to repel them or heal the ship. Especially since you need to first upgrade your scrap capacity a couple of times, to even be able to afford either of these vital purchases (at their base price, which then also ramps up).
I also found maneuvering around the ship rather difficult.
With that said I do have to emphasize, slamming into meteors and chaining from one to another was IMMENSELY SATISFYING.
I'm also impressed you managed to make a rather good 3D within those time constraints. Oh and your ship model is really nice too.
TL;DR Fun game, wish it was a bit easier ^^;
