Finding Non-Flash Portal Games

Flash is dead (EOL Dec 2020). "Portal game" could mean several things:

1. Games Like Portal (Valve's Puzzle-Platformer)

• Official: Portal 1 & 2 (Steam, console)—native, non-Flash, best experience.
• Similar Mechanics: The Talos Principle, Q.U.B.E., Superliminal, Viewfinder, Portal Stories: Mel (free mod), Thinking with Time Machine (mod).
• Browser (HTML5/WebGL): Portal: The Flash Version remake on Poki / CrazyGames (fan-made, no Flash).

2. "Portal" as in Game Portal Websites (Non-Flash)

• Steam, Epic, GOG, itch.io: Native clients/HTML5.
• Poki, CrazyGames, Y8, Kongregate (HTML5 section): Curated HTML5/WebGL/Unity games.
• Newgrounds: Ruffle emulator runs old Flash; new HTML5 uploads.
• Armor Games, Addicting Games: Migrated to HTML5/Unity.

3. Portal-Themed Indie Games

• Portal Knights (Action RPG), Portal Walker, Aperture Hand Lab (VR demo).

Clarify what you're looking for (Valve's Portal clones? A site to play games without Flash? A specific game named "Portal"?) and I'll give direct links.
