I've had the pleasure of testing out the platformer DASH: Danger Action Speed Heroes for a while now and it's truly shaping up to be an impressive game.
Legend of Shara is the first full expansion for the colourful roguelike RPG Tangledeep, it adds in a huge amount of content and it's worth a look.
Tate Multimedia have just recently released Urban Trial Playground, a stunt-bike racer with same-day Linux support.
One funding campaign I completely missed was Crossroads Inn, a fantasy tavern simulator that managed to get fully funded. It looks pretty good and it's coming to Linux.

Crumble from developer Brute Force popped up on Steam recently and honestly, it looks like it could be a really great 3D platformer.

Not long to wait for another really good looking point & click adventure game, as Guard Duty is releasing with Linux support same-day on May 2nd.
The latest game in the Kingdom series, Kingdom Two Crowns, recently had a big update which came along with a beta for Linux gamers.
Flippfly (Race The Sun, Evergarden) have announced Cats Fly Helicopters, an amusing sounding game about being a cat flying around a simulated city full of physics and emergent gameplay. On the topic of Linux support, they had some comments for me when asked.

KeeperRL, a dungeon simulator with a mixture of roguelike and RPG mechanics had another massive update at the end of last month.
Puzzle games don't get much more streamlined than this, Jetstream has a very easy-going atmosphere combined with super simple controls making it easy to get into.
I see Drink More Glurp as one of those games that's going to cause a lot of laughter and shouting as it does look rather amusing.

Currently in Early Access, Wheelz2 is a 3D moto-trials game inspired by some of the 2D classics like xmoto.
