Sarafan: Keep in mind that Steam accepts almost everything to its store, even games which doesn't meet any quality requirements. I'm not trying to say that Selaco will be a bad game of course, but I just want to show the differences between the two stores. I don't think that a request for a playable build in this situation is something inappropriate. What more, I don't see how sharing this build with GOG would be unfair to the backers. There's zero chance that this build will leak, so no one from the community will have access to this game before the backers. I think it's an overreaction from the developers. If they fear that it'll be unfair to give GOG access to the game before the backers, they should wait with it until the demo is released for the people who funded the game. This will solve all of the problems.
Yeah, I know about Steam situation, some games are not even games at all. And I understand that Steam is too big to notice it or to remove *inappropriate* games without a second thought.
I don't think Selaco is a bad game, videos, showcase limited to patreons, and frequent communication from developer team all are very convincing that it'll be something spectacular, it even have the RTX (I have no idea what it is, but it sounds cool). I agree about build and like I stated a few posts above that build should not be disrespectful to backers since they will get more polished version anyway, even the pre-demo playtesting phase is not active yet. I have no idea why that decision was taken so swiftly (several hours), and I don't know how I would react in their place in case of GOG's requirements and prior ignore for 2 months when Steam with more projected sales don't give a dime about my builds of plans for DLCs but accepted it nonetheless. But I see that other publishers / developers worked their way to GOG anyway, so...
Yes, developer should have waited for a demo indeed, even the early access demo would not betray backers since it's only 1 month period difference at best, maybe some would feel betrayed I can't speak for them of course.
I hope that one day developer will resubmit the game again, this time with playable demo.
The question is when demo will be ready, my guess in 2 months (it's only my speculation).
