Like the other user here, I would buy this on GOG in a heartbeat.
I bought and played the inferior Switch version in 2018 on the eShop. I've always thought the game was really good fun that was only ruined on the Switch by extremely blurry visuals that were enough to give me a headache; though I still managed to complete the game eventually.
I know the game is better then that, because I also played it on PC Game Pass in 2019 and it was a much better experience on my laptop. I've been a DRM-Free-only and physical-only gamer for the past 5 years and have wished Snake Pass were on GOG ever since discovering it. I would buy it physical on PlayStation, but there was only a Super Rare Games physical release of the gross Switch port. I've been dying to replay it on PC for a few years now, but I won't buy it on Steam.
