In Chapter 2, the red BALLS still emit blue light. Also, when you win, you can't move the mouse anymore. That is probably because you need to unlock the mouse when the player wins or dies.
Another problem I had was that the light was pointing down, which made it really annoying to try to see and not in a good way that enhances the horror atmosphere.

I really liked Chapter 3. I don't know why, but I preferred the new monster, even if it's just a little different. I also feel that the menu is better, especially the Play and Quit buttons. However, I don't understand why the game's name changes.
P.S. I did not find Pepino. Where is Pepino? I demand PEPINO!
