Summary

Sunkenland has a TrueGG Rating of 72.5%: the positive share among 881 reviews written in the last 180 days by players with 10+ hours. That is 7.9 points below Steam's overall 80.5%, so players who really play the current version are harsher than the headline number suggests (all time: 84.5%).

Reviews written under 2 hours make up 9% of the total, and only 45% of them are positive. Some players bounce off early, but those who get past the opening rate it higher. Steam accepts refund requests within 2 hours of play and 14 days of purchase.

Negative reviews most often mention 未完成・手抜き (less than at launch) and boredom. Positive reviews praise how fun it feels, 難易度, and バランス.

Among Japanese-language reviews, the TrueGG Rating is 77.5%, similar to all languages.

Re-weighting reviews by trust signals (playtime, length, how the game was obtained) barely changes the rating (80.1% adjusted), so Steam's number is not noticeably distorted by key giveaways or throwaway reviews.

All figures come from Steam's public review counts, and topics are counted with our published dictionary (no AI). Data as of 2026-10-19.

Why it is rated this way

What drives the rating

Complaints center on technical quality (Unfinished / low effort). They have declined since launch, so things may have improved. It is also a game many people bounce off early (early reviews are much less positive than those of players who stuck with it).
