I'm looking for small indie games on PC that are still mostly unknown and have sold very little but are actually good

Okay, on the subject of the weekly sale, here's some stuff worth taking a look-see that's on sale right now.
A metroidvania-type game with the kind of careful combat that assholes these days like to call Soulslike. Not really mostly unknown, but still fun.
Adventure game from the guy who made Deadly Premonition. We will never get a sequel.
You know that game Super Buster Bros? It's that.
This one allows you to create your own spells by combining spell parts that each have a different quality. So you combine a fire spell with a poison modifier and a homing modifier and you can basically guess what you get. Or there are ways to create black hole spells that explode, or summon robots that explode into ice, or other stuff you get the idea.
An actually pretty cool lightgun rail shooter based on an indie comic book.
