Nice update, especially the onboarding and system changes.
If I was testing this, I’d focus on:
- tutorial rewards (first-time vs replay, making sure they don’t duplicate or fail)
- mute system persistence, especially since it’s tied to browser storage
- party system + MMR behaviour across different queue types
- login/onboarding flow for new vs returning players
- cached data (leaderboards, profiles, friends) to make sure it doesn’t go out of sync
The login and caching changes feel like the kind of thing that can look fine at first but break in edge cases.
