Extracurricular Activities boasts a varied cast of (mostly) likable characters, but is hampered by its verbose and often clumsy dialogue.
The available love interests are pretty well characterized and each of them brings a different relationship dynamic to the table. However, the game never fully delivers on the dynamics and kinks that it teases throughout. For example, one love interest has a serious submissive streak while another presents as a hyper-dominant top, yet neither route offers the option of an actual dom/sub relationship.
This issue is present on every route so far, where the characters discuss their kinks, agree that they'd both enjoy that kink and then never really commit to it.
The game is also pretty leisurely paced, with lots of scene dressing and mundane conversations that don't really advance the story in any way. Conversations around and about food are an especially prominent example of this throughout the whole game
The art is great overall, with the notable exception of the player character himself. He's not hideous or anything, but a lot of his sprites make him look goofy. The CGs and the sexy bits are overall good, but strictly vanilla.
Overall, a good read with some great art and lovable characters. As long as you're okay with a rather large slice of life in your sexy VNs, Extracurricular Activities will keep you entertained for days.
