I've had this game in my list to pick up ever since I got a ps4. However I only ever buy discs, so maybe this is a good sign that it will finally be available in my local store.
It'll probably still be very difficult to find physically, as it only had one limited release and that sold out almost instantly.
Fortunately, if you're not interested in the digital PS4 copy, you can purchase a DRM free download from their itch.io [1] which works on Windows, Mac, or Linux. Its a game that would run on a toaster, so not having a gaming computer isn't a barrier.
KRZ only had a limited physical release through iam8bit and it sold out shortly after it was released last year. Though it looks like it's also included in a collector's edition bundle of games from the publisher, albeit at a very high cost: https://www.iam8bit.com/products/annapurna-interactive-delux... It's also available DRM-free from GOG and Humble Bundle (the Steam release might also be DRM-free, but I haven't checked).
