Fun game! The graphics were really nice, and I especially loved the concept of shooting each part of a fish only once. This made taking aim really crucial and the gameplay interesting. Although it lagged once you started going deeper, I feel like you still could have done more to make the game a bit longer, especially with the journals. I liked the fusion of Motherload and flOw, but some upgrades just didn't feel worth it, especially the harpoon, since I had practically beaten the game by the time I got it.
The story was interesting, but I don't feel like it was up to the quality standards of your other work. The hunter becomes the hunted, okay, we've seen that before. Maybe I'm missing something. I feel like Carney could have done better when it came to the music, too. Somehow the mood of the game didn't really capture me the way your other games have.
Even so, this is a very original and fun game!
