- Breakthrough Hit: Holdover is seen as one for Fox Eye, as it is the most well-known game from their catalog among the doujin gaming community and very likely their introduction into Fox Eye, as well as their most accessible game outside of Japan (to vouch for this, the games main character, Marie, has had more fan art of herself than any other Fox Eye protagonist despite having a lower amount of official art from the circle, itself). Being a challenging freeware Metroidvania helped with that.
- Doing It for the Art: This circle is heavily creator-driven. Although Fox does encourage the circle's fans to support and buy the games he develops, he's has such a passion for underwater fantasies that he's willing to share free artwork of his characters to his fans from time to time in the circles social media outlets. Also, while nearly all of Fox Eye's games have the common Fanservice trappings of what can be encountered in other Ecchi and Hentai works (such as Buxom Is Better, Clothing Damage, Stripperiffic, and Level-Up at Intimacy 5), and that some fans believe that Fox can make a bigger profit off of his games by focusing on those tropes and other Hentai-esque tropes even more, fetish material involving Under the Sea exhibitions and drowning perils still remain Fox's top priorities due to both of them being the circle's biggest sources of Author Appeal, and the keys to their Signature Style in the Doujin Soft community.
- Line to God: Previously, you could have Japanese or English conversations with Fox in his Twitter account, where he tends to discuss the progress his upcoming games as well as small aspects of his personal life. He also occasionally posts exclusive artwork of characters from some of his games, or even draw new ones. However, the Twitter account was suddenly suspended with little to no chance of restoring it. So Fox moved the circle's social networking outlet into Pawoo, which is an alternate form of Twitter that is powered by Pixiv. Check it out, here.
- Milestone Celebration: On March 2nd, 2018, Fox posted commemorative artwork featuring a crossover between several of Fox Eye's regular, event, and Abyss heroines from 2013 to 2017 for the circle's 10th anniversary. What makes this more Heartwarming is how this happened after Fox made a full recovery from an illness at the hospital a few days prior to the milestone.
- No Export for You: The original Blue Port, Mermaid, and Sufferer: The Final Escape have yet to receive an English translation, and are consequently harder for English-speaking players to obtain and understand since those games are only purchasable in the Japanese version of DLsite. All of the other games have averted this, either because they're in the store's English version or because they're Freeware Games.
- Screwed by the Network: After over half a decade of direct communication between their Japanese and English-speaking fans, Fox Eye's Twitter account was suddenly, and permanently, suspended. This was apparently because of some riots that accumulated on Twitter that were against the aquaphile-pandering material of Fox Eye's works (most likely the circles well-known emphasis on drowning perils). Fox then decided to move the circle's main social media outlet into Pawoo, which has a similar structure to Twitter, and continue with public updates there for the time being. When some of the followers of Fox Eye's now-defunct Twitter account were alerted to this, they subsequently made their own Pawoo accounts just to continue following their favorite doujin circle from there.
- Teasing Creator: The trials of some of Fox Eye's games come off as this for the developer towards players who are getting into the games for their drowning fanservice.
- In Barely Breakout!, the puzzles of Levels 4 to 6 are scenarios that involve freeing a girl trapped underwater before she drowns. In the trial version of this game, those puzzles are locked out.
- In the trial of Sufferer: The Final Escape, you can only play its Tutorial Level, which also happens to be the only level in the game (and possibly the entirety of Fox Eye's catalogue) where the protagonist has Super Not-Drowning Skills. This is because Yuna's Oxygen Meter never falls below half its length in that level, where she would've otherwise begun struggling for a breath.
- Hades Vanquish is a Double Subversion. Its trial version does allow itself to show Mana drowning once her Oxygen Meter completely runs out, but then it cuts out to an ad to buy the full version before Mana's drowning animation ends.
- Vaporware: Sadly happens with this Doujin Soft developer from time to time, though some ideas and concepts made for these games may eventually be realized in other games:
- A Blue Port 2 (which would've been more of an open world game compared to the original Blue Port, which can also be seen in 2011's Blue Port J) has been planned by Fox for years since the release of Holdover back in 2009, with several work-in-progress pics◊ and multiple development blogs about it. Many years and several more games later, it still has yet to truly become a reality.
- A 3D Stealth-Based Action Game involving an blonde Action Girl named Kureleuille, who wielded a high-tech handgun, was also previewed in the past.◊ This game never came to be, either, but the concept of a blonde, gun-wielding Action Girl reappeared a few years later as Hades Vanquish's Mana, who then saw her own successor as the blonde, dual gun-wielding BLUE GUARDIAN: Margaret.
- There was another 3D Action Game announced in 2017 that starred a Ninja girl named◊ Nene◊, but afterwards, there was no further news of the game until 2019, where despite its progress, the game was also put on hold due to Fox not being satisfied with its current quality. Fox may plan to use some of its assets for a different game, however.
