Extremely addictive. The controls are literally perfect. The way the ship has a lot of momentum forces you to think strategically, making it very different from a lot of similar looking games.
The graphics are not really as good in my personal opinion. I feel like there are too many conflicting styles; some things look really simplistic, while on the other hand stones and fuel tanks are little 3D renders for some reason. It's also really strange to see how the ship has wings, but they don't actually seem to have any part in steering the ship. There are also several planet surfaces that look kinda ugly. But in the end, we don't play for the graphics, so it doesn't matter as much.
Another minor nitpick is that there is no easy mode. I think it would really help if there was a game mode where the game was just a little more forgiving, because this game (mostly because the controls are so unique) is very hard to get in to. I am afraid some people have given up on this game simply because of the fact that there was no easy mode. And that can only be described as a tragedy.
The level design is sometimes questionable. There are some enemies that are pretty much unable to harm you due to the way they are positioned. While at other times stones in particular can really gang up on you, making some parts of a level disproportionately difficult. So sometimes the levels feel a little bit random, as though not too much care is put into it.
Though sometimes the contrary is true. There are some little bits of level design that are simply great. Usually, when it's a level with a lot of blue-laser-shooting enemies, you can see that you really put some thought into it how big the distances between each enemy needs to be. Very good work. But the red-laser-shooting enemies are just kinda there most of the times.
But all-in-all, it's one of the best games ever.
