We have it ready, but it is not unsealed yet. Come back when it opens.
Opens on 2026-08-15 (JST)
Spend 30 days on an alien world, allocating each day to a handful of small actions. The memories you accumulate, not any single choice, decide which of 9 endings you reach.
Per Steam's own listing, this is an SF slow-life novel adventure about spending 30 days on the planet Pipisera among a cast of distinctly individual alien beings. Each day you allocate to shopping, part-time work, socializing, or travel, and these varied actions accumulate as memories; the store text is explicit that which memories you've collected changes which ending you see, currently nine of them, and just as explicitly states this is not a romance game. One playthrough runs about ninety minutes. Made and self-published by the solo developer Mareffy, whose four-title Steam catalogue is entirely self-developed and self-published. Priced at ¥1,500, it is Positive at 100 percent across 13 reviews (13 positive, 0 negative), a paid title, not free, fully launched and not in Early Access, with no AI-generated-content disclosure and Steam's content descriptors completely empty. English and Japanese are both supported, so nothing is stopping you. One honest note up front: 13 reviews is close to this site's floor, and no genuine English-language coverage exists yet, on AUTOMATON WEST or elsewhere. Every one of them is in Japanese; not one is in English, Chinese, or Korean.

01First, the one feeling
- Being told outright that this isn't a romance game while every action still feeds into which of nine endings you see reframes what the relationships in the cast are for; they're not routes to win, they're just part of how thirty days adds up.
- Splitting your time across shopping, work, socializing and travel, with no single action weighted as the 'right' one, means the memories you end up with feel like a record of what you actually chose to spend a month on, not a strategy you optimized toward.
- Nine endings from the same thirty days is a real invitation to notice what a different allocation would have produced, less a puzzle to solve than a life you'd live slightly differently the second time.
02Who this is for (and who it is not)
For you
- You want Princess Maker's core idea, that an accumulated span of time rather than any single choice decides the outcome, applied to a fixed thirty days instead of years
- You want a slow-life sim that explicitly isn't about romance, where socializing is one memory-generating action among several rather than the whole point
- You want small and self-published: solo developer Mareffy's four-title Steam catalogue is entirely self-developed, content descriptors completely empty
Not for you
- You want a settled number; 13 reviews is close to this site's floor even at a perfect score
- You want a game already found in the West; every single review is in Japanese, and no English coverage exists yet

Give it your first passPrincess Maker The origin
The origin of this taste: Princess Maker, the game that established the raising-sim genre, where a fixed span of time and a handful of categorized actions accumulate into one of many possible outcomes, no single choice deciding the whole. Dandelion Planet is not an official Princess Maker work, but it carries that same core structure into a very different shape: you are not raising a daughter across years, you are the traveler yourself across thirty days, and what accumulates is not stats to be optimized but memories, deliberately kept apart from romance, that decide which of nine endings you land on.
