Story of the last 7.5 years of my life.
Well, I mean critique is valid regardless of someone paying or not, it's just kind of weird how people simultaneously say "western porn games are garbage quality" then turn around and go "games should come out immediately, cut content, dont bugtest, just put it out" etc.
So the reason you can't pre-purchase it is because Steam has two ways to put your game up on it;
- Normal Way (what we did) where you can wishlist it, but you can't pre-purchase it, you can only buy it when it comes out
- Early Access, where you can effectively pre-purchase it
The reason why we didn't do Early Access is because that's mainly for games that aren't even close to being complete, and it's expected that you'll be getting new builds to play with, give feedback on, etc. as a tradeoff for pre-purchasing.
Since we didn't have much else to put out build-wise by the time we got on Steam (as everything remaining was either A) back-end stuff like the Achievements system (not Steam achievements, our own system), getting in sound effects/music/voicework, bugfixes, etc. or B) spoiler-heavy stuff like story things, the true final boss, final gameplay areas, etc.), we didn't want to go Early Access and then just not put out any builds.
There's a lot of other algorithm-based stuff that means Early Access wouldn't work well for our game too, but that's the main reason.
Wishlisting it though really does help a lot!
