HEXATAIL has always prioritized atmosphere, and Agent17 -v0.23.8- introduces dynamic lighting shadows.

If you’re a current player, update immediately. This patch doesn’t add new story branches or major characters, but it makes the existing experience significantly more stable. For new players, v0.23.8 serves as an ideal entry point—most of the early-game friction points have been smoothed over.

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.
