There's no point for me in criticizing something that wonderful as Akira points, it just can't be done objectively by a biased person like me. The influence of that game spreads further than just an ordinary game, it became my golden standard for all porn games and stayed it for already a year, an example of how you should make them. This came doesn't deserve any other rating but excellent, but if I could set more than 5 stars for that - I'd do it. It's so outstandingly good that I can't compare it with other porn games, numbering the stuff it did right, would take hours for me and an unforgivably long text wall. So, instead, I'll just share a few of my thoughts about that game below.
1. Most of the game you will spend with Akira in the MC's apartments. The game's duration is around 4-6 hours, depends on how fast you are reading and how you're gaining your Akira points. It would feel quite boring to play in the same circumstances over and over again, but it feels very natural and interesting - honors to non-H scenes. Something has happened at work? College life issues? Household routine? Just some random event happened? - all of it makes the pastime in this game so interesting. They build some kind of lore or decorations in which players can dissolve. It is a huge achievement even for an ordinary short visual novel, not talking about a porn game. Thus said, spending your time with Akira feels like you are spending time with your roommate, not as a sexual object, as a human being.
2. What comes to sexual encounters, both MC and Akira are talking about their feelings, emotions and constantly reflexing on them as individualities and as a couple. Wondered why the story was so wholesome? Well, that's the main reason. This is also a huge achievement of the authors because it is very hard to maintain both pornography and sweet romance at once (heck, lots of authors can't maintain even one thing).
3. Have you ever noticed how everything that happens in Akira points is so consistent and reasonable? Why Akira gives you the points? Why she's teasing you for so long? Why she even came to you in the first place? Even the gameplay elements (mini-games) are integrated into the story very well. It sure may seem to have quite big issues with capability with reality, but it is impossible not to notice the effort authors put into making that storytelling fluid and consistent.
I think that'll be enough, for now, although I'll always feel that I haven't said enough about that game. As I see it now, it is a really small game, but playing it made me feel like I'm playing something really big and breathtaking. If you'll be afraid that this game is not one of your kind and that it has way too much story, but not enough porn, don't be - Akira is very rewarding, as you can recieve a lot for her points.
