When people play
Average concurrent players by day and hour over the last 15 days, shown in .
Daily activity peaks around 14:00 — a pattern consistent with a player base concentrated in East & Southeast Asia. Steam publishes no per-country player data, so this is inferred from play times.
Audience
Language mix of 100 Steam reviews spanning 3 days — a rough proxy for where the player base is.
Achievements
Every achievement in the game, ordered from most to least earned (#1 is the one the most players have). Height is the share of all players who have it; the dashed line is the median. Global rates from Steam.
