Btw, I preffer 3d games, not browser ones. I would like a game that's easy to pick up and a run wouldn't last more than 1 hour

if you like Roblox, either Doors, Pressure or any "get a snack at 4am" type game. I can't really recommend any other games but i would say The Complex : Found Footage is also a pretty easy game to pick up (as it was one of my first games i've picked up, i can confirm this myself) or any Amanda The Adventurer game.

Portal is fun, and pretty easy to learn the basics
