So I just saw this, and am genuinely stoked. The first Sheltered was one of those random games I came across due to a youtuber I follow, and it looked neat, and I ended up loving the hell out of it. I've got over 200 hours in it, and never can bring myself to uninstall it, just in case I get an itch to play it again.
And now they're making a new one! And it's not just a side scrolling, retro 8-bit thing. No, they're putting a significant amount of work into upgrading the various elements of the game, but they still feel very familiar. Basically the "what you had before, but better, and with more stuff."
So, yeah I'm eagerly looking forward to this one.
