Good concept, and good story. The graphics are also not bad, but I would have preferred if you drew them yourself instead of using stock photos.
Not really much of a "game". More just a series of animations you watch and then click next, next, next. Yeah, there are some multiple-choice questions that pop up, but since there's only 1 correct answer, the outcome never changes. It would be more interesting if the player had some control over what actually happens. For example, what if I could really chose where to land? Or what if there was some challenge to planting vegetables? Letting me decide which order to complete the missions is a nice start (shame there's actually only one mission) and having to complete a mouse-maze to build the rover was a good idea (shame only two levels are completed so far). But there are hints of elements of a good game hidden in here.
You've got a strong theme and story to work from. I would suggest cutting back on some of the boring parts, and focus on the interactive gameplay elements. Give the player meaningful choices to make, and more challenging tasks to complete.
I look forward to seeing this completed.
