Happy Hand did an excellent job localizing the game, the grammar was good and he went out of his way to make sure the game was brought to us in its entirety. The gameplay is fun enough for an h-game and the scenes are good and varied. It is a little short, but I think the quality makes up for it.

Pros
-Reasonable variety of scenes, both in action and character
-Good h-scene and costume art
-Game begins feeling like it has some challenge and resource management aspects

Cons
-Story is very weak
-Combat/adventure art is very poor quality
-H-scenes use "invisible penis" which isn't to everyone's taste
-After gaining a few level ups, combat is comically easy with most combats, including final boss combats, being resolved in less than 5 seconds
-Lack of challenge and formulaic repetition of quests removes any sense of progression and replaces with straight grinding (very fast but very unrewarding grinding)
-Ultimate weapons (only unlocked in post-game) are bugged to be uncraftable. This is effectively irrelevant because there is no post-game content to require them, but still frustrating from a completionist standpoint.

Black Train's art is amazing! There isn't much to actually "play," though. You get just three skills during the battle and every skill you can unlock becomes obsolete when you learn a high-EP skill and abuse Azel's Orgasm invincibility. That being said, the game's scenes and plot will have you sticking around 'till the end.
The game's presentation also shows that it was made by very competent people. I have no doubt they could make something if they invest more time and effort in the game's mechanics. If they "worked a bit more under the hood," you could say.

Gameplay's pretty good better than the average rpg maker game. This games got 30 eroge scenes and whole scenes a majority of them are surprisingly consensual.

Surprisingly enough its good a pretty good story in it and not only that but a lot of original sprites.

Beyond that heard there was going to be a DLC or some sort of prequel.
