I like the 3D model of the main character and the cute illustrations during conversations!
The shooting part is easy in the beginning because ghosts appear less frequently, but after the middle of the game, they appear in large numbers, which is interesting because you have to think about building up your skills from the beginning.
And I was playing the windows version at first, but in the middle of the game I got an error drop due to my PC's low performance. Then I tried the web version, but it was too slow and I couldn't stand the rush of ghosts at the end of the game and lost.
I think the windows version probably failed because I was taking a video of the game, so next time I will try to clear the game without taking a video of the game.
