Yo! So I tried your AVN and I was pretty happy with it.
I enjoyed the sense of humor in it and also the quality of the graphics.
The idea of the Portals is fairly unique for an AVN, I have seen similar ideas but nothing exactly like this one. Should be interesting.
On the other hand I think the choices in this AVN leave something to be desired. Mostly It just seems to be a slow build up of affection/relationship points... which I assume will eventually lead to unlocking lewd scenes with a particular girl... But is that all it is? If thats the case then I will be disappointed.
I hope that you avoid that trap, its an illusion of choice because it doesn't actually change the plot in any way.
I hope to see actual plot changing decisions instead... For example: what if the MC and his friends can change the fate of the worlds they visit but its dependent on what choices you make as a player? Maybe if you choose to save a particular NPC it turns out they can help you save that world? Or contrary-wise they could betray you and doom that world?
Anyways another question I have: Is this a Harem game? Or am I expected to choose just one girl?
