Their latest game, Firmament was a bit of a let down. The puzzles were far too easy and the game was far too short. It felt like they spent a lot of time making it look pretty, adding VR support, etc instead of just making good puzzles.
The one before that, Obduction, was pretty great. I really loved it.
I feel they're still putting out stuff that's just as good, it's just the market has moved on.
