Feels a bit incomplete and unconnected. The guy gives the girl a flower and then it's just never mentioned again. The animation is OK. I don't play PUBG so I guess some of it went over my head. The ending joke was pretty funny, but I wouldn't recommend using the same joke twice like you did with the heavenly music. You could leave out the flower thing, it really serves no purpose to the story. Either that, or reference it somehow. This way you have a setup but no punchline.
