I also love short-ish games, so hopefully one of these strikes your fancy. You didn’t specify a preferred genre or other games you liked, so I’m going to just throw some out there:

Adventure/Puzzle

• Stacking - fun adventure puzzle game based on matryoshka dolls
• Little Nightmares - fantastic puzzle game stuff great atmosphere and horror elements; similar to INSIDE and Limbo
• Abzû - underwater exploration with light puzzle mechanics
• Ys 1 and 2 - pretty old, but it’s my favorite Ys game; Ys Origin is a bit newer, but also a bit longer (~11 hours per playthrough, need 3 for full story, but each plays differently)

Puzzle

• Manifold Garden - puzzle game where you manipulate gravity
• Hexlogic - sudoku-like
• SUPERHOT - shooter that plays like a puzzle game
• Magrunner - just ignore the story, the puzzles are pretty good
• Portal - the OG puzzle game, must play if you haven’t; second is about twice as long

ARPG/Souls-like

• Death’s Door - just started, but it’s looking good
• Ittle Dew - Zelda-like with lots of satire about the genre
• Furi - boss rush only
• Titan Souls - boss rush, but both you and the boss has 1HP

Narrative heavy

• Telltale Batman or The Walking Dead - narrative heavy game with walking simulator sections; choices matter (but not a ton); great if you want a decent interactive story
• What Remains of Edith Finch - explore your old home to learn everyone’s secrets
• Oxenfree - explore Island to uncover its secrets; replay value for alternate endings

Metroidvania

• Headlander - Metroidvania where you play as a disembodied head that can attach to other bodies
• Ori and the Blind Forest

Point and Click

• Darkside Detective - point and click with a great sense of humor
• Broken Age - you’re a virgin about to be sacrificed, and you’re not sold on the idea
• Deponia - earth is completely wrecked, and you want off; quite funny

I have more, just let me know what you like and I can try to give more recs.
