About Lily of the Valley Unofficial Ren'PY Remake

This is a Ren'Py reworking rather than the original release, and the card marks it abandoned, so version 1.7 from March 2021 is where development stopped. The first build is dated 2 March 2021, with an update a day later. Eighteen tags describe the content, covering 3DCG art, animation, an RPG structure, corruption, housewives, netorare and a long list of scene tags.

Art is listed as 3DCG and animated, and the protagonist is female, which follows from the tag rather than from a story summary. The RPG tag suggests a progression layer alongside the dialogue, though the card records no detail on systems. English is the only language, and the censored field is set to false, so the listing carries no censorship notice.

Four platform builds are listed, which is wide coverage for an unfinished fan project: desktop packages plus an Android option. No download files are attached to the entry at the moment, so this page tracks the latest release and will show the 1.7 package when a link is added. The card reports more than a million views.
