What other sources say
| Source | Their take |
|---|---|
| Steam disclosure | AI content disclosed |
| AI judgment deepseek-flash | AI-assisted · AI scope: parts · effort risk: lowReasoningThe store disclosure states some backgrounds and illustrations use image-generating AI, so AI assets ship to players. That is a limited share of a small action platformer with 19 mostly positive reviews. The developer has only two games, both disclosing AI, and no high-volume release pattern. Against: Only two games released, so the shared AI disclosure is not evidence of mass production; most assets and gameplay appear conventionally developed. |
