Solid patch, this is the kind of stability work that really improves the overall experience.
I’d recommend testing:
- how save/continue behaves in different situations (mid-upgrade, relic shop, after game over, etc.)
- whether rounds always end correctly now, especially after edge cases
- ball behaviour after loading, to make sure nothing gets stuck or disappears
- UI consistency when moving between game, menu, and continued runs
This feels very state-driven, so I’d focus more on transitions and odd scenarios rather than just straightforward playthroughs.
