Evaluation

Incremental Epic Hero (IEH1) launched on Steam on February 22, 2021 as a free-to-play idle RPG that had previously reached one million plays on Kongregate. After launch, the developers at Hapiwaku shipped a series of content updates: a major Steam launch patch (February 23, 2021), new Curse of Reincarnation challenges (March 9, 2021), quality-of-life improvements (March 25, 2021), new 4th Reincarnation Skills (April 15, 2021), and the Expedition & Artifact system (July 4, 2021), which introduced idle mechanics and was described as a foundational update for future expansions. However, from July 4, 2021 onward, the developer's focus shifted decisively toward Incremental Epic Hero 2 (IEH2), a fully new sequel game. The April 2021 developer message confirmed IEH2 development was underway. By April 2022, the team launched a public playtest of IEH2. In the April 25, 2022 news post, a message from developer Kei explicitly addressed IEH1's future: "The next update is scheduled for around August of this year. Also, we will be doing some collaborative updates with IEH2, so stay tuned." This is the last developer communication referencing any IEH1 update plans — and that promised August 2022 update never appeared in the news record. All subsequent posts from 2022 concern IEH2's playtest and Early Access launch (July 22, 2022). The last confirmed content shipped to IEH1 was the Expedition & Artifact update on July 4, 2021. The developer's attention moved entirely to IEH2, and the IEH2 Support Pack DLC (released March 28, 2021) was explicitly sold as a way for IEH1 players to support IEH2's development. All five DLCs are released with no unreleased items listed. The game is a complete, finished product — it launched as a full game, received post-launch content updates through mid-2021, and then development quietly concluded as the team transitioned to the sequel. No further content has been announced for IEH1, and there has been no developer communication about IEH1 since April 2022.
Evidence
The Expedition & Artifact update launched, introducing major new idle mechanics. Developer Kei noted this update restructured the save system 'for continuous updates in the future' and teased upcoming challenge bosses — but no such updates were ever published in the news record.

We are Japanese game developer team Hapiwaku Project!
Hapiwaku means "Happy and Excited" in Japanese.
We hope you are so happy and excited through playing IEH!
We are very small team. The developers are only 2 university students.
Most of the art work in the game are drawn by my 13-year-old daughter.
We write the stories behind the development on our website :)
