I think it's good, but I only played it on PC one hour or so I can only compare to that.
Visually it looked much better on PC, no shit huh Also it ran more smooth, not surprising either.
But I think the port is great, it works great handheld. I recommend not playing it on the difficulty I choose (hardest possible from start, I guess the other two are unlocked when u finish the game) because according to Digital Foundry more enemies are spawned. So less good framerate. Play it on normal or easy. I'm dying ALOT and it's probably not getting easier later on
I couldn't tell the difference between the PS4 & Switch versions, undocked, it really runs so smooth and looks amazing!!! The online multiplayer part is a bit cheezy and cheap, I must admit I didn't like it.. felt really dodgy.
