Also, another demo I played on the deck was White Knuckle, downloaded after Jerma streamed 8 hours of it. I wasn't expecting it to work with gamepad controls but the default scheme got me using ALL of the deck control features for the first time.

Back buttons? Check. Gyro? Check. Trackpad? Also check.

And somehow it still (kinda) works, props to however set up the control scheme.

Downloaded the Ratatan demo and yeah it's the perfect steam deck game. The only thing I didn't like is that it felt like wasn't able to react to the enemies, like every time an enemy showed the "ready to attack" animation I was in the middle of another command so it felt a lot like "Attack and pray for the best".

I don't remember if patapon was also like this but a wider attack animation window would help a lot.

Regardless I'm buying the game day one since it feels like a rhythm game drought these days lol.
