Really cute design! I really loved it. I think this game has tons of potential. I could imagine a similiar approach as in "A game about digging a hole" here, but with a semi-open world to explore instead. The photos you take give you money, money allows you to upgrade your camera or hiking gear, allowing you to explore new areas to take photos of "more difficult" animals which in return give you more money. I think that could really spice up this game.
The style is perfect as it is, there's nothing to change about it imo. The only problem I had with the gameplay was that the camera wasn't rotated exactly as the player's model rotation, felt a little off when switching the camera. But besides that tiny issue, very cool game, well done!
