I didn't know there was a Switch version, but that's a shame. I'm pretty sure you can get it fairly cheap on the various Steam key websites, if you don't mind entering the dark side.
I dont mind paying a little more to get it legit really.
A sale always happens eventually I can wait, no rush.
Sides by the time I get a Steam Deck there is likely to be a good sale or two.
Sure wish a physical Steam Deck version could happen, I'd like to collect it.
Still tempting to get the Switch version for collecting but eh rather play the game at its best.
