Evaluation

Time Tenshi launched on November 20, 2015 as a complete standalone visual novel. The developer, Silver Cow Studio, has never announced any DLC, expansions, or additional content for this specific title. All news posts on this game's store page relate to either the original launch or announcements of separate, standalone follow-up games in the series — Time Tenshi 2 (June 2016), Time Tenshi Paradox Episode 1 (December 2017), Episode 2 (April 2018), and a reimagined "New Time Tenshi" (September 2020). None of these represent post-launch content additions to this original game; they are separate Steam releases. There are no unreleased DLC listings, no roadmaps, and no developer statements promising future content for this title. The game launched as a finished product and has remained so.

About this game

The Time Window...

An incredible invention, developed over decades in secret, empowers humans to make their grandest dream a reality...

To travel through time!

At a hidden research facility, Rose and Kyo - the Time Tenshi (Time Angels) - voyage into the past in secret under the watchful eye of Tensai Shiro, the mastermind behind the Time Window, and Michelle, the base's Commander and Operations Manager.

Since time travel is still dangerous and experimental, the Time Window has yet to be tested on male subjects, meaning only females can safely venture back into history. They seem to undergo some surprising changes to their bodies in certain areas while doing so...

But a sinister organisation called Chrontek found a way to hack into Shiro's machine, and now Chrontek is pursuing its own devious plans for the flow of time...

Can time travel be entrusted to humans?

What happens when the Time Window goes wrong?

And can the Time Tenshi stop the girls of Chrontek... before history is changed forever?

Time Tenshi is an exciting anime/ecchi visual novel! As the player's character enters Tensai Shiro's lab facility and follows the Time Tenshi in their journeys through time, a plot full of futuristic action, ecchi, humour and plenty of fanservice will unfold!
