Nice twist.
I was a little disappointed to see this movie kick straight off with another fight at first, as I was expecting some answers to questions the first one left. Such as why these giant monsters exist in the first place, why they're made out of tofu and why some guy is fighting them. Fortunately the ending you came up with was a nice little twist, which got rid of any disappointment completely. It also served as a much better ending than the previous one, as this time you ended with perfect timing. The ending has got me really looking forward to seeing the third in the series, as I expect it will answer all, or most of my questions.
The fantastic visuals obviously had a little less impact this time with me having just finished watching the first in the series, so it was vital that you delivered something other than just a fight this time round. Story is so often missing from fight-based movies which end up becoming series, so excellent job on including some.
The purple tofu monster seemed to remind me a lot of purple tentacle from Maniac Mansion and its sequel Day of the Tentacle. Was this a nod to that character?
