Design risks
| R1 | Compulsion-loop pressure | 0.00 | |
| R2 | Monetization | 0.00 | |
| R3 | Social risk | 0.00 | |
The game appears to have very low risks related to monetization, with no microtransactions, loot boxes, battle passes, or subscriptions. Social risks are also minimal, as there is no stranger chat or other explicit social features that could lead to social obligation or competitive toxicity. Content risks, specifically violence, are present given the 'Fighting' genre, though the severity cannot be determined without further information. There is no indication of manipulative compulsion-loop mechanics.
