Halcyon Days: Sunny Days with Sister-chan

Editorial Has potential

Halcyon Days is a stat-raising visual novel centered on intimate progression with a sister character, where players unlock scenes by managing affection and acceptance through dialogue and physical interaction. The game has clear route design—a consensual path, a forced route, and an unconscious route—with dedicated players finding substantial replay value once they understand the mechanics. However, the build is genuinely rough: widespread reports of crashes on Wine, persistent touchscreen bugs on Joiplay (with workarounds required), missing save-file documentation, and an incomplete feature set. The developer has been transparently communicating delays and is actively working on promised content, but the current state is unfinished and technically unstable for many platforms. If you can tolerate technical friction and don't mind an unpolished experience, the character art and route depth have their audience; otherwise, wait for a more stable release.
