good cheap game recommendations?

I've heard Bad Rats is very good, you should try it.

Legend of Keepers: Welcome to the Dungeons Company
Next up is this

Super Beast Hunt is a well-made 2D platformer, and it's free.

Define cheap! Base price cheap? Sale price cheap? Keyshop cheap? Or you want F2P recommendations?
Also, your profile doesn't really tell much. It is 3 years old with 260 hours played. I almost played Baldurs gate 3 this much in 3 months.
But as far as I see, you enjoy third-person action adventures and 2d figher games, is this right?

These seem like a perfect match for you:
Singularity
Hotline Miami
The Darkness II
Dishonored

These seem like a long shot:
Nuclear Throne
Max Payne 3
Call of Juarez Gunslinger
Borderlands 2

Is there any particular genre you’re looking for?

F2P
Armillo
A nice short top view platform game, originally a paid wiiware game, now free.
Exception
Awesome 2d action / platform game, originally priced at 12€, now free.

I recommend to use https://gg.deals/ or SteamDB. Make yourself familiar with their tools and you'll easily manage to find the best deals for games that should interest you. It's certainly better for you on the long run if you can use such tools yourself.

Not that there's anything wrong about general suggestions, I just wouldn't expect strangers to drop a list tailored to your preferences on demand. Wait for the big sales on Steam and you'll see threads popping up, full of recommendations.
