Look out there:

Formarly known as "Ravensdale" (which was orginally a working title for an awesome but cancelled RPG-Project at Spellbound) which got a failed Kickstarter-Campaign, BlakckForestGames now polished out the project, made an already playable demo (at the bottom of KS-page) and, most important, will only aim for 50.000 $ as a goal.

Well, I think I´ve only missed two things:
It´ll have DRM-free Online-Coop AAAAAAAND:
Go playing that demo! NOW!

Will it? This reads like "we're going to eventually sell a steam-free version that will use our multiplayer server software that we aren't going to provide, and we reserve the right to shut down the server and leave "drm-free" customers without multiplayer when we see fit".

For me it reads like...

We cannot afford server-infrastructure right now, but we´ll definitvly release a DRM-free Version, that has coop included but you can only use after we´ve set up the servers.

That's not DRM-free coop, though. DRM-free coop is when you the player can host your own server. I understand having to wait until this functionality is independently implemented, but that's not what YOU'RE saying. Seriously, their own quote is more favorable because "set up this infrastructure" might be very charitably interpreted as "write and release steam-free server software". Them setting up actual server instances with those servers being the only 2+machine coop option is DRM.
