I own it on Switch. I wish I could play it on my Deck without having to re-buy from scratch. I understand maintaining each platform has a cost, but they could think about a small addition, rather than a whole re-buy. This of course is valid for each game, not just this one.

Here's hoping my old saves will still work with the new content

Absolutely adore this game and its concept. ConcernedApe and the way he continues development both encouraging modding, enabling others to add to the creativity and updates years and years after it's release.
