Nice update, especially this close to release.
If I was testing this build, I’d focus on:
- cloud save consistency across devices and sessions (especially switching between PC and Steam Deck)
- leaderboard accuracy and fairness, particularly with difficulty differences and run timers
- performance stability after the optimisation pass, especially under heavy effects or in browser
- boss behaviour during spell casting (immunity + timing interactions)
- tutorial flow to make sure new explanations actually match what the player experiences
The cloud saves and optimisation changes feel like the highest risk areas, since they can look fine at first but break under normal use.
