Well done! Graphics are consistent and I liked how the music evolves as the player progresses.
The jump feels a bit floaty, but with all those sneaky penguins roaming around, I understand that Mr Bear here had to develop exceptionnal jumping abilities.
Oh, and the fact that he fishes with a fishrod too haha that made me laugh =)
I think that the bear's collision box could be a bit smaller, that would help for some jumps that requires precision.
I also really appreciate the narrative justification for hp. The fish you carry is your actual hp instead of traditional hearts and damage.
