lots of great suggestions in this thread, just wanted to shoutout this little indie i played and had a delightful time with: Flynn, Son of Crimson

it's a little 2d adventure game with pretty linear progression, although there will probably be some backtracking if you want to 100%. but it's level based and not open world at all. the movement and combat both feel pretty good, the story is very fluffy and feel good, and you have a giant dog as a pet, what more could you want?

it's probably like a 15-20 hour game in total, if that. a great time if you want something short, fun, and uncomplicated
