It's been a week since the game was released.
I analyzed the reviews and comments on the store page and made a small update to the game:

• Added the ability to navigate in the main menu and pause menu using the mouse.
  
• Due to numerous requests, improved the readability of letters in the book - now they have a white background.
  
• Made some optimizations, as the game was running slower than it should on high-resolution monitors.
  
• Added the ability to switch to windowed mode with the "F" key in the main menu.
  
• Adjusted the ghost's hitbox; now it is positioned lower than before.
  
• Adjusted the depth of mushrooms relative to the character.
  
• Fixed some words in the control localization.
