Viability: the game is playable from start to end, with a straightforward progression and a variety of endings. The system is not particularly complicated, but there are a few moments where the player can determine the outcome (particularly at the end), so it is certainly an improvement over the first prototype.
Presentation: The voice acting and character art is compelling, and adds to the already charming expanded script. Oddly enough, adding voice acting instead of background music made the stakes feel more real, even if the game in general is pretty relaxing. The layout remains serviceable, but I am sure could be made more unique and tidy with the proper CSS design. It would also be great to have some fun ending art, but I understand the time limitations. In all, a strong presentation.
Theme: it is charming and sweet, with a good sense of humor and interesting characters. Adding Millie and Hydra Z was smart because although they are both nice in their own way, their personalities are not just “bent” towards the player. The theme is much stronger now that we have a variety of people that, although are all nice, have different world views and attitudes.
Engagement: Due to the linear structure, the game can be explored after just a few sessions. They are very fun sessions, however, and overall there is a definitive sense of closure to the experience. Time permitting it would be awesome to create a more open structure, where people can explore the island and meet each Kaiju more than once, in different situations.
