Agent17 (v0.23.8) , developed by HEXATAIL, is a story-driven adult visual novel and sandbox adventure. Centered on a high school student who discovers a mysterious, high-tech smartphone, the game allows players to command an enigmatic, elite operative known only as Agent17 to manipulate their social surroundings and gain influence.

Mini-Games & Tasks: Gameplay is supplemented by activities like tailing targets, casual games (dice, rock-paper-scissors), and combat sequences.
Character Management: Players interact with a diverse cast—including classmates like Luna, Ruby, and Erika—to unlock unique "H scenes" and story progression. Features in v0.23.8 Agent17 -v0.23.8- By HEXATAIL

HEXATAIL used v0.23.8 as a dedicated bug-hunting pass. Notable fixes include:
Agent17 arrives like a midnight courier: lean, deliberate, and humming with purpose. v0.23.8 is one of those small-but-satisfying updates that rewards both tinkerers and operators—thoughtful polish where it matters, and a few bright sparks that change how you feel about the tool.
HEXATAIL has hinted that v0.24.0 is in active development, with a focus on expanding the school hub and introducing a new recurring event system. For now, v0.23.8 is a “cleanup before the storm” release. Bug Fixes & Stability HEXATAIL used v0
Players of earlier builds noted that once you broke line of sight, enemies were too easy to lose. v0.23.8 introduces a “last known position” memory system that lasts 45 seconds longer on harder difficulties. Now, guards will:
This change forces a more patient, methodical playstyle—exactly what HEXATAIL intended.
A new secondary antagonist, codenamed "Specter" from the rival agency Chimera, is introduced in this version. While not fully fleshed out, v0.23.8 includes a prologue mission where you intercept encrypted files. Dataminers have found voice line placeholders suggesting Specter will be a romance-able rival in v0.24.0, but HEXATAIL has neither confirmed nor denied this.
Released earlier this month, Agent17 -v0.23.8- focuses on three main pillars: performance optimization, new side-missions, and AI behavior overhaul.
Version 0.23.8 introduces a completely revamped mobile interface. Given that many players experience Agent17 on Android devices via APK, the touch response lag has been reduced by 40%. The new "Agent Log" (a quest journal) now color-codes missions by urgency—Red for main story, Gold for character-specific arcs, and Silver for random events. This eliminates the previous frustration of wandering aimlessly through the city map.
In a recent development diary, HEXATAIL hinted that v0.23.8 lays the groundwork for multiplayer ghost mode (asynchronous leaderboards) and a “New Game Plus” that carries over key items. Version 0.24.0 is expected to add a fifth playable character with unique dialogue trees.
