Steam version

Nicalis also announced this last night on Twitter:

Did you already get NightSky on Steam? Yes, as in NightSky is now available on Steam!

I bought the game before it was on steam. Is there anything between the non steam version and the steam version? Did they add anything?

There's been no mention of steam-exclusive features or levels, to the best of my knowledge. The entire practice is pretty "un-Nifflas-like" aswell, I'd be very surprised if there was anything like that.

The versions are identical.

Any way I can attach my non-Steam version to steam? I mean a proper attachment as if I had purchased it, not just adding it as a "non steam game"

You can buy it. But as far as I know, Steam doesn't offer a way to attach a license code to steam itself so you can download and install the game. If this is possible, please let me know too, because I actually have bought a game I already own in steam at a discount because I'd like to have it in steam too.

as far as I know, there's an option to "redeem" games you bought elsewhere when they're out on steam too, but that requires a special serial key which the publishers give you. at least that's how it was with the indie bundles, so yeah. I guess not?

Did a bit of searching. This might be the solution: https://support.steampowered.com/kb_article.php?ref=5414-TFBN-1352

Apparently you can do this but only for a small selection of games. (See this list) and they don't go for indy games at all.

Basically, you cannot transfer your license to steam for Nifflas' games because Valve doesn't support it.

that's what I was talking about, I think.
