This is a really solid entry, doubly so for a game jam! I like the focus on narrative and emotion. I felt like each "wave" of seals just missed grabbing me, which made me feel like I was playing well, though at the expense of the other penguins.
Not sure how scripted it is, and I'm sure some of the magic would be exposed on more playthroughs, but for a first time playthrough I was invested. Good job, both of you!
