The game might seem grindy and too time-limited, though please do not forget that you've played the demo, not the full version. We can't just open everything, so our demo limits your time. In the final version of the game you'll certainly get enough time to obtain most of the pictures during one playthrough.
We're still working on the world, trying to make it more attractive, there's a plan for more special events, and more places which need your stats to activate.
Thank you guys for giving us the feedback.
As we're still working on the game, it is highly recommended to give us as much feedback as possible, so we can keep improving our dear game. Best regards!
