These games are on sale for pretty cheap, can't remember the prices but Axiom Verge is the only one that is $10 (normally $20). The rest are like $2.50-$5
Steamworld Dig
Steamworld Heist

I think the sale ends tonight at midnight though but they're all solid games if you're trying to scoop stuff up.
I also got Whispering Willows for cheap too but I think the sale ended last night. That game is pretty cool, pretty basic spooky horror-type adventure game but the art style is good and the sound design is great w/headphones.
