Iβll start with a few minor issues. At the level with the colored buttons the game began to feel a bit repetitive for me. I did not memorize them right away, died, and did not feel motivated to replay that section again. There was also a moment early on where I tried to close a door just to test things, but it did not respond. Later, near the red button door, I stood very close to the left button and when the door opened it pushed me into the wall. I was worried I might get stuck there between the wall and the door, although the door eventually closed. On level two, in the camera area on the right, I noticed a chrome-like object. I am not sure if it is explained later, but during gameplay it felt a bit distracting.
Overall, I really enjoyed the game. Your interpretation of the theme feels fresh, with a subtle 2000β2010s vibe and a strong Hitchcock-style suspense. Also reminded me a bit of Severance and The Stanley Parabel. The experience is very engaging, I enjoyed figuring out signs from the βbig brother.β The death sounds are a perfect finishing touch and add a lot to the concept.
My only suggestion would be to introduce another mechanic later in the game to keep things fresh and maintain the playerβs interest.
Really great work!
