TLDR: An oldie, but goodie that could use more polish.
I want to first say: the entire written story was created by
George Tasker (if you like this game's story, please consider reading his other work!) as a choose-your-own-adventure game over 15 years ago. There may be some girls you've haven't heard about in a long, long time or maybe even ever. KlonHad has kindly converted the game into HTML and added a few GIFs to spice it up, but there is otherwise nothing new. The passages are copied/pasted directly from the old CYOA.
Back to Secret Agent School is a light-hearted, goofy spy romp filled with sex. You can either play as a bumbling buffoon with a knack for sexually harassing your female co-workers or his sexy, sometimes naive, female partner. It is relatively short and there are very few options- you're looking at a play-time of under an hour, maybe even 30 minutes.
I have to say, this was like playing an old retro-game and realizing that while it was innovative and fun at the time, you now want much more. To help make this old gem shine, it needs GIFs and sexy images for every scene, it needs more written options and an expanded story. If I could, I would give this 3.5 stars, because as is, it's still a fine game and a nice trip down memory lane, but with the love and support of a new writer/developer, it could be much more.
