Update for v1.4.2
Since 1.3.1, Wape has polished the game a good deal. Gone are some of the bugs I'd encountered. Most importantly, though, he implemented my suggestion of prioritizing undiscovered endings over discovered ones. This has a tremendous impact on the fun of trying to "collect them all". He also added an enhancement to that allowing one to choose an ending after reaching a certain attainment.
Additionally, he added some fun new content. Well done, all round.
Review of v1.3.1
I've been tempted to try this game many a time over the years it's been in development. As far as I can tell the author pops up every once in a while with an update. But his own warnings about the content always scared me off. But even without having played it, it was evident that it contained several of my preferences: Male MC, dominant MC, supernatural MC, harem, impregnation, real porn. I finally decided to try it expecting to pretty much close it right away.
And while I suspect the non-con aspects of this game are probably it's primary focus, I'm really happy and surprised to report that it's quite playable purely seducing your targets! I wouldn't dream of saying you can play a nice guy, but at least you can get endings purely from seduction and without violence.
The writing is quite good and definitely hot. English errors are present but infrequent and not distracting. The game mechanics are actually pretty fun. You gain powers according to how you play which can be used to give more options with other conquests. I'd say this part is done very well. However, the game is definitely designed around multiple playthroughs.
You probably have to like or at least tolerate AIF, of course, to enjoy this. It is almost completely text via Twine/Sugarcube and the little vids do little more than spark your imagination. Even though I like AIF, I'd suggest that a few more images for each scene would be welcome.
It would also be nice if you could back out of routes when it becomes evident that you cannot succeed using seduction. Save scumming does the job for now, though.
Obviously, because of my preference, I'm hoping the author will continue to add girls and have seduction or at least hypno routes for as many as possible.
I'm sure there will be plenty of reviews covering the non-seduction routes, so I'll leave that to those who enjoy them. However, I suspect they are at least as well written.
Overall, a fine effort by the author.
