Holy moley, that's a lotta 'mons! O.o
This was a neat little adventure, and I think the thing that really seals the deal for me is the Pokedex-like entries for each of the little creatures. Personally, that was a HUGE incentive for me to catch new 'mons even though I was already satisfied with my party.
I do kinda wish the gameplay evolved a bit more as it went on (I played it for quite a bit and found that I didn't have to change my strategy all that much), but I still find it absurd how much content and depth you were able to pack into a week!
