Got all the fruit in 39 days. Now I really don't understand how the game clock works. I beat the game earlier at 11:50, then continued from the day before, got all the fruit, beat the final boss again. Clock says 11:46... Apparently it didn't account for the fruit collection time after beating it once?
Simultaneously, I've done some mission mode. It's so addictive, much more than I though! I tend to get silver the first try, gold the second, and then it takes a couple of more runs to optimize the run well enough to get everything (got 5 platinums so far). And at that point it's impossible to quit before beating the level, because you know you can do it.
It would've been nice though if there were also levels that can't be "completed" so that you'd really have to consider whether getting this or that. Now you know you have to get everything, and it's "only" a question of order and method. Not complaining though, really good stuff.
