Ah, we're actually doing real recommendations now. :-)
You can find excellent games by sorting by rating: https://itch.io/games/top-rated (they may not all be to your taste, but there are many real gems here.)
My personal candidates for the possible best games:
Paid (though you may have gotten them in a bundle):
https://vlambeer.itch.io/nuclear-throne (action roguelike, infinite replay value and high skill ceiling)
https://dinopoloclub.itch.io/minimetro (mostly relaxing high score puzzle management game)
https://adamgryu.itch.io/a-short-hike (awesome short adventure)
https://devolverdigital.itch.io/pikuniku (very funny short adventure)
Free:
https://teamsalvato.itch.io/ddlc (Doki Doki Literature Club: beautiful and disturbing - not for children or for the faint of heart)
https://ninja-muffin24.itch.io/funkin (Friday Night Funkin': high quality rhythm game)
