[Kizi] [2015] Old game based on a boy and his dog.

So I remember playing this game as a kid, in middle school somewhere around like 2015 probably. It was a game with the boy and his dog, you’d move across the screen through obstacles and stuff. I remember at the end of the game the last level was in black and white and it was raining and there was some sad music in the back, you had to like swing across the screen or something there was a hole in the floor I’m pretty sure. If anyone knows what this is please lmk, it drives me crazy!

Also I think I remember the dog being tan and possibly fluffy, it was like a 2D game though im pretty sure.
