NinjaThea: Steam Deck Friendly!

[p]NinjaThea now plays on Steam Deck thanks to latest updates:[/p]

• [p]Linux build (obviously!)[/p]
• [p]Improved controller support (menus and gameplay)[/p]
• [p]UI scales properly on all resolutions (including 1280x800)[/p]
• [p]Bigger, clearer text in UI[/p]

[p]I hope this makes the game a bit more accessible to players. Enjoy![/p]
