I watched the trailer without any prior knowledge of the game. Here’s some of my thoughts.
It’s basically a moon lander game. Music and overall mood is OK, but you could tighten up the editing. Takes are pretty similar, so the video would fit in 20-30 seconds without any crucial information being lost.
If there’s some specific twist or uncommon game mechanic, you should probably concentrate on that. For example, one short scene of each feature mentioned in your game’s description: “rescue survivors”, “recover resources”, “settle a new planet” and “allow your people to thrive”. Total four takes.
But I think that’s a technically good start. TV-commercials are usually around 30 seconds long, and you’re going to notice that it’s extremely hard to summarize anything in that duration (especially without lazy explanatory texts).
