That was a nice little horror adventure. Yes, this game is actually creepy despite the cute 2D artstyle. Not extremely scary, but it has a very dense and eerie atmosphere.
Armed with only a flashlight you play as the little sister searching for her dog Poro and her missing older sister in a town full of ghosts.
The gameplay in general is basically exploring the town while trying not to die. Your most common strategies are hiding in bushes or behind signboards and... running for your life.
There are also a few usable items you can find and throw, like rocks to distract some ghosts and animal food to feed cats.
There are many different enemies and they all have their different traits. Most are only visible under light, some only react to sound, etc.
It also has 'boss fights'.
Some parts were a bit annoying in their trial-and-error nature, but in general it was fine. There's also lots of optional stuff to discover. It's a 6-10 hours game I'd say.
