Tools built on data we collect ourselves
Every number on these pages comes from Steam's public API and is stored in this repository as raw JSONL, so you can recompute anything we show. Nothing here is copied from another fan site, and nothing is estimated.
Live player count
Current players, peak and low for the sampled window, and the full reading list. Sampled every 15 minutes.
Open the player countAll 16 achievement rates
Steam's global unlock rates, ordered as a difficulty ladder instead of alphabetically, each linked to the guide that explains it.
Open the achievement tableGift deadline calculator
Tell it which day you are on and it tells you which gifts can still arrive in time, and which scenes you have already lost.
Open the calculatorAvailability status
Whether the game is on sale right now, with each claim dated and sourced. No shutdown speculation.
Open the status pageWhy these four pages exist
A fan wiki normally competes on how many pages it has. We cannot win that, and players do not need a 200th retelling of the same walkthrough. What no other TSUMIMI TIME site has is a dated, reproducible record of what the game's numbers actually are: how many people are playing, how rare each ending is, and exactly which day a gift stops counting.
