That was a nice experience.
The slightly unusual gameplay takes some time to get used to, but becomes quite enjoyable afterwards. Changing a planet's trajectory mid-course with a meteor that was carefully placed in advance is particularly pleasing.
Considering the tight time limits, randomizing some of the obstacles was probably unnecessary, as it made some attempts a bit harder than others. A quick restart button would also be a welcome addition ( unless there is one and I missed it ).
Overall, really solid entry, albeit a bit short.
