Fix for button glyphs not showing on steam deck

Simona's Requiem is:

• A short and sweet game. Expect 2-3 hours of gameplay.
  
• Medium difficult. Most people should be able to pick it up and finish it.
  
• A chill experience. The pace is deliberately a bit slower than other fast-paced platformers.

Simona's Requiem is not:

• A traditional Metroidvania. It has more in common with Simon's Quest than Symphony of the night.
  
• Jam-packed with content. Our goal has been to make an experience that can be fully appreciated in one evening.

Features

• A mysterious world awaits you to explore. Discover a decrepit land lost in time unlike anything else and meet its strange inhabitants.
  
• Upgrade your abilities to conquer new challenges. Find new ways to traverse the environment and help you overcome all challenges.
  
• Find secrets hidden all around the world. Relive past events through collectible epitaphs found hidden all over the world.
  
• Battle many different enemies with your scythe. Simona wields the Moonlit Scythe, a slow but versatile weapon more than capable of taking down the most ferocious of foes.
