Clean Up Any Mess You See
Alba: a Wildlife Adventure is more than about taking pictures as Alba, it's really about doing the right things, giving the game positive vibes. When exploring, it's good to be observant and pay attention to your surroundings in the game because you never know what needs tidying up.
If you see some trash on the ground, you'll see some prompts meaning that you can pick them up and put them in the trash can. Doing so will reward you with achievements and it's also just really satisfying to do believe it or not. Plus, it makes you feel kind of good, right?
Among other things, you might see some clothes hanging on lines. You can take these and put these in the hampers nearby (don't worry, nobody will tell you to get off their lawn). But keeping things clean is a nice side activity to do aside from taking photos and enjoying the open-world and story.
One of the fun things about Alba: a Wildlife Adventure is that you have plenty of freedom when on your search for images to capture. And you'll be able to hop into your adventure very quickly once you complete the prologue portion of the game.
One of the big things you should do is complete goals, and one of those goals typically means taking pictures of different types of animals. The best way to do this is to simply be thorough in your search when exploring the game world.
Check high and low, as certain animals can be tough to spot sometimes. I saw a gecko one time, but it was kind of hard to spot due to how small it was. Also, make sure to approach animals carefully. You can tiptoe towards them and then use your phone to zoom in to get a good snapshot.
Talk to Locals
This is not a necessity, but there are several NPCs with who you can have brief chats. On many occasions, it will just be small talk. That said, you may get a chance to meet some new characters or read some interesting, funny, or wholesome dialogue.
Again, this is a small part of the game, but it's pretty fun to hear what folks have to say. Almost everyone has a chat bubble floating overhead, so why not see what they have to say, right? Alba: a Wildlife Adventure is not an uber-rich dialogue experience, but sometimes locals might be helpful, you just never know.
