Start with the bottleneck
Do not spread early purchases across every branch. If missed targets and short runs are the problem, start with consistency. If the run survives but earns too slowly, move into income scaling.
A flexible purchase order
Use this as a decision order rather than an inflexible build.
- Comfort or stamina support
- Reliable income multiplier
- Area or speed synergy
- Luck only after your spawn volume is healthy
When to hold cash
An upgrade purchased just before an urgent bill may never repay its cost. When the timer is worsening, compare the upgrade price with the amount still needed and preserve a safety margin.
