Honestly, the best game I've played so far in the Jam. I couldn't stop until I had caught all eleven memories.
You applied the "Timeless" theme to memory, and it works beautifully (I used a similar approach in my game :)).
The game conveys a deep sense of melancholy, enhanced by a carefully crafted atmosphere. The ending is both emotional and bittersweet. Visually, it's perfect. Everything feels detailed and immersive. I don't know if it was intentional, buy I used the position of the mountains and the moon to orient myself (such a clever touch).
The fishing rod upgrades are also spot on, pushing you to improve in order to reach certain memories.
All in all, a fantastic project. Congrats on the work and best of luck in the Game Jam!
