The last eroge I've played is Sexy Demon Transformation. It took me quite some time to finish this VN, not because it was long, (it's short) but because this game is so bland with its typical dialogue line and overused trope, it has managed to make me fall asleep in front of my laptop. It is an achivement on par with Koihime Musou battle system, in which it's only good point is for sleep inducing. (The similarities lies in the sleep part.)
Nevertheless, I did manage to finish it in one sitting and half of the h-scenes in this nukige are good enough to keep me going.
I'm just going to list the bad and good point of this game. (It will contain spoiler.)
[spoiler=Bad Part]Yep, bad part first.
1. BGM and Sound. As expected in a nukige here's nothing memorable or anything about the music, but what made me listed it as the bad part is that the Intro music is too loud when I run the game. Clicking the left mouse button to skip the intro solve the problem but it still irks me. Urgh.
2. The dialouge line and narration in h-scenes doesn't match the CGs. Best example is the toilet h-scenes, the narration said that it was a "white dick" (because it's toilet paper) but the CG shows a black dick instead. -_-"
3. Half of the h-scenes is stupid. Strictly the h-scenes for the 2 girls from newspaper club whose names I've forgotten because they both sucks. Boobjob scene could be done much better imo. And the flying sex scene are just plain retarded and awkward.
4. It would be good if all of the h-scenes is fully animated instead of just a small few. It's a let down.
5. I dislike censored CGs but I hate bad art more. Uncensored CGs with bad art are just shit.

Just like this one here.
6. Guessing which demon trigger an event and choosing which location you want to go, this "gameplay" bored me. They could've done something better.
7. Two of the characters is a nuisance. (Yes, the two annoying girls from the newspaper club. Especially the one with the camera. Oh, her voice are so irritating...argh.)
That's all for this part I guess.
[spoiler=Good Part]
1. Asuka and Yukihi H-scenes are pretty good and I like it. XD Huhuhu~~~
2. Plot? What plot, this is a nukige! Well, to my surprised this VN actually has a funny story. It's just too bad that the storylines are simply childish. And the fact that I fall asleep once because of those two girls boring dialouge didn't help either. But the stories are still better than most Nukige so this is good actually. Hahaha.
3. Ah, the possibilities. Becoming invisible and inserting you thoughts into other people, merging with the wall, transform into a toilet paper (Hahahha...rofl), and become a ghost so that you can pass through wall and stuff and then materialised your....ah, this is a pervy imagination. It seems that they executed this one very well in this game.
The End.
tl;dr
Let's just skip to the score then. I'll give this VN a 3.5 at least.
