I played Superhot first on the Deck. Since time only moves (much) when you’re moving, you have lots of time to practice aiming and getting used to track pads/stick + gyro controls. It requires precise aiming, and there are occasional times where speed helps, so it was a good “training” game for me.
It’s still not as natural as KB+mouse, but I’ve been enjoying Ziggurat 2 a lot (on normal difficulty). I won’t push into hard modes, like I would on PC, but it’s working well for me.
