Got all 30 parts in 28 days.
I really enjoyed this game. I liked the puzzle style and did get quite a few chuckles out of his descriptions of the various ship parts -- "I don't know exactly what this thing does, but it was really expensive, so it must be good." The end boss (really, the only boss), was a decent enough challenge, given the method in which you attack things -- it took me about 15 tries to defeat it. I briefly tried out the Challenge Mode, but simply trying to get as many seeds as possible in one day did nothing for me.
The two biggest issues I had with the game, and which keep it from being a 9 or 10 out of 10, are
1) the inability to easily control the camera at will (you can, but it's tedious)
2) the time limit becomes really pointless and more of an annoyance than anything else
The time limit for each day just caused me to make sure that I always had at least as many parts found as days elapsed, and if I didn't, I would just reload from that day. Some days I would just spend figuring out how to get to the next part and then reload and go directly to that part. And on the final stage, I basically "wasted" a day opening the path to the boss, which only took about a quarter of the day, so I could just make a straight path to it from then on.
Minor annoyances:
It would have been nice to be able to skip the landing and take-off animations at the start and end of each day. Since they are relatively short, it's not that big of a deal.
Not being able to skip/speed up text, especially when he kept making the new discovery of what happens when the seeds the Pikmin brought back to their Onions would take the Pikmin count from under 100 to over 100 in the field -- he made this discovery about 10 times over those 28 days.
I'll definitely be picking up Pikmin 2 whenever I find a CiB copy.
