Players need to explore the town in order to find Poro and her elder sister. To do so, a flashlight is needed to illuminate her path and to look for useful items. Anytime you find an item of interest, a question mark (?) will appear to indicate that it can be checked, which will later change to an exclamation point afterwards.
Players can use items such as stones, money and a shovel, depending on their needs. Stones can be used as thrown items or landmarks, the shovel to dig up specific spots such as sand and money as currency to be used in certain places, such as peace offerings. The heartbeat system is used to alert players if a monster is nearby, making the girl move slower and force her actions to be limited. The only way to hide from the monsters is to evade them after observing their patterns or hide in areas like bushes and wait for them to go away with the heartbeat serving as a de facto radar to locate where the monsters are while relying on sounds to make a judgement call to see if its safe to come out of hiding.
