Klaus is a precision-based puzzle 2D platformer with a self-aware narrative. It's tight & challenging platforming takes inspiration from precise classics games combined with a tense and emotionally engaging story. Along with another playable character called K1—a friendly brute— he embarks on an existential journey, exploring the idea of the fourth wall and awareness of the player playing the game. Featuring 6 worlds, 34 levels, 100+ rooms. Two playable characters with unique skill sets and cooperative gameplay. Hidden collectible levels add even more depth to an already emotional story.

The game features mild violence and language, typical for an E10+ rating. While challenging, it does not employ manipulative compulsion-loop mechanics or monetization schemes. The narrative's philosophical themes are unlikely to pose significant social or emotional risks.

  • DSA:What Ludograph checks: whether the game's design gives minors the transparency the EU Digital Services Act expects: plain terms, honest defaults, and clear reporting routes.: Estimated from review data. No dark pattern or child-targeting concerns found.
  • GDPR-K:What Ludograph checks: whether age assurance and consent flows are designed for under-16s, in the spirit of GDPR Article 8.: Estimated from review data. No privacy or child-targeting concerns found.
  • ODDS:What Ludograph checks: whether paid random-reward drop rates are disclosed, as required in China, Japan and South Korea.: Estimated from review data. No paid random-reward mechanics found, so drop-rate disclosure requirements do not apply.

These reflect Ludograph's assessment of the game's design practices against each framework's criteria, not a legal compliance determination.

Parents ask…

Is KLAUS safe for kids?

Ludograph gives KLAUS a rating of 78/100, recommended for ages 7 and up. It scores well on developmental benefits with manageable risks.

What age is KLAUS appropriate for?

Ludograph's rubric recommends a minimum age of 7+ for KLAUS, based on benefits, risks, and content review. That is more lenient than ESRB E10+: industry ratings reflect content intensity, while ours also weighs how the game is designed to be played.

How long should kids play KLAUS?

Our session recommendation for KLAUS is up to 120 minutes per day. It is derived from the game's own structure (natural stopping points, compulsion-loop design, monetization pressure, and social dynamics), not from a universal screen-time dose.

Session recommendations are design-based heuristics. Evidence linking specific daily durations to child outcomes is limited, and context matters as much as time; treat this as a starting point for household rules, not a clinical threshold.

What are the main risks of KLAUS?

The game features mild violence and language, typical for an E10+ rating. While challenging, it does not employ manipulative compulsion-loop mechanics or monetization schemes. The narrative's philosophical themes are unlikely to pose significant social or emotional risks.
