There are a few technical glitches and errors here and there but considering the time table for making this game, I'll just focus on commenting on my experience with this game...
Graphics may put off some people (you know what demographic I'm talking about) but once you got over it, "Ah! My Girlfriend is a Demon Summoned from the Depths of Hell!" is a very pleasant and enjoyable experience. The voiced characters really do make a whole lot of difference but Makoto's stands out as the most well fleshed out. The accent is oh... how should I say it... it just feels so natural...
For some odd reason, I can feel the MC's irritation all the way from here especially when one of the Twin Devils shows up and a mere few clicks later, another one shows up... and another... Overall I sort of knew what I'm about to get when I downloaded this game and get it I did and some more... and it's great overall... oh and, the ending is a bit abrupt... too abrupt...
