I never expected to see "I got reincarnated… as a hamster!" as the opening line of a Steam description. After crossing that threshold, seeing a warning for "frequent nudity or sexual content" was equally unexpected. However, this is the reality for Sweet Hamster Days, a Japanese visual novel where you're a pet hamster doted on by three sisters that is officially back on Steam.

The Return of Sweet Hamster Days

The game is currently planned to release in Q3 of this year. This marks the second time an official release date has been announced, following a period of uncertainty.

As the developer posted on X in late 2025, the title was previously pulled from Steam "due to various circumstances" before its original winter 2025 release window. While the exact reason for the removal remains unclear, it is notable that storefronts like Steam are increasingly policing mature content.

You will be able to find the game on several platforms:

  • Steam
  • Epic Games Store
  • DLsite

A Unique Live-Action Romance Sim

If you are unfamiliar with the premise, Sweet Hamster Days is a "live-action romance sim." Players take on the role of Kota, a man who has been reincarnated as a hamster named Hamta.

The gameplay focuses on your life as a beloved pet to three sisters. Your goal is to use Hamta's "tiny paws and big heart" to help mend a growing rift between the siblings.

Mature Content and Gameplay Expectations

While the premise sounds whimsical, players should be aware of the mature themes. The Steam page explicitly states that the production contains scenes featuring characters in swimwear and other revealing attire.

The game also hints at a romantic element, suggesting you will "fall in love" with one of the girls. While it doesn't appear to be an explicit animal sex game, it certainly isn't a purely wholesome or platonic experience.

Personally, I find the romantic angle a bit disappointing. I often envy the lives of my pet guinea pigs, who spend their days eating and napping. A life of pure snacking sounds lavish, though I suppose hamsters do have to deal with the endless cycle of the running wheel—which feels a bit too much like a 9-to-5.
