A fun sideways space scroller with some neat mechanics. After I got about 40,000 score, there were so many rocks that it was hard to progress any further. I like the inclusion of a character (ship) selection and the ability to unlock all of them in the settings. While I was playing the game I was wondering exactly how far I had traveled. It would also be nice to have some invulnerability frames after getting hit, as sometimes I would run into the same rock multiple times and take lots of damage.
