The steam version lacks 1 NTR animation. That's the whole difference.
People love to exaggerate and escalate everything.
Except nobody is exaggerating anything. Look, I don't like dev bashing, I always find it childish and useless but here you totally deserve those negative reviews. You can't just cut content out from the game because of a vocal insecure minority (that scene was already optional), publish it as being a different version (Steam) and be surprised about the reviews when people find about it.
So to get that content back, I need to get the game elsewhere but by doing so, I'm missing out on the "exclusive" content from Steam. (Btw, doing different "exclusive" content for different storefronts is kinda scummy...).
I respect the work you've done, I was interested in buying in the first place but I can't support censorship. Hopefully you'll consider adding the cut content back in with a free DLC and make a COMPLETE Steam edition (seriously... get rid of that "exclusive" bs).
