Looking For a Portal-esce RPG

I’ve been playing varying RPGs with a friend group for long enough that we’ve not only switched games, but even switched main GMs. We also regularly play little one offs (usually a modified Lasers and Feelings) when we’re down a player and over half the group has taken turns at running these.

I’ve finally gotten the courage to want to try running one of these one offs and am looking for a loosely prewritten story I can send them through. You are more than welcome to suggest first time pre-writes that don’t fit my weird description, but I’m picturing a Portal-esce story where I can send the players through challenges, study their actions with sassy commentary like GLaDOS, and they hopefully outsmart me and escape. If any of you have suggestions, they would be greatly appreciated.
