Hidden my game by mom

The game starts with the young boy protagonist sitting on the floor of his house, smiling and grunting while obsessively playing a video game on his portable game console (reminiscent of the Nintendo DS). The door behind him opens, revealing his mother, who looks cross. The next day, the young boy looks for his game console in his house to no avail. He exclaims that his mother has hidden his game console.

The young boy has to overcome increasingly absurd obstacles in order to find his game console in the following days. He succeeds in finding his hidden game console every day for the next thirty days. On the 29th day, he jams the door a baseball bat (which he grabbed from a baseball player), locking his mother out of the room.

A thousand days later, he continues to play his game console every single day, as trash pile up in the room. The boy (now older and larger) finally unblocks the door and opens it. It is revealed that his mother and the rest of his family has been waiting patiently outside his room. They hug, and the camera zooms into the opened game console. It turns on and reads, "Escape the room success!"

A short video linked to at the end of the game shows an extra ("omake") ending. Someone is shown grunting and playing the video game console once again. The mother tracks it down to find out that it was actually the grandfather, hiding in a closet with the game console.
