Welcome to Itch! It's full of all kinds of games of all levels of polish, genres, etc. so you're bound to find something you like.
But, since your preferences aren't exactly aligned with mine, I can't give you anything that's that up your alley. But, as others are sharing their own games, perhaps you'd enjoy strategizing and putting together the most optimal defenses to survive an onslaught of pirates in my game Recolonizer (https://forloopcowboy.itch.io/recolonizer). It's quite the opposite of experimental, and not exactly a puzzle game, but it will definitely make you think about how you go about defending your island.
As a developer, I enjoy selecting the same tags as my own game, and going on the Most Recent tab and seeing what other people are making. It's fun to engage with other people's creations, and see at what stages of development they are. I will warn you to avoid downloading executables. Unless I'm feeling adventurous, if the game is not browser playable, I avoid it.
