The first snapshot is particularly easy. This places you in a bonus level and tasks you with finding all ten diamonds. Flying around the edges, then checking the middle will collect them all. Use
to rotate and
to accelerate. If you've played Asteroid before, this should be familiar.
The snapshot mentions doing this before your fuel supply is exhausted, but fuel isn't really impacted until you've been aimlessly flying around crashing into walls for a minute and a half; with no prior knowledge of the game, I had completed the snapshot in just under a minute.
