Start with the upgrade panel
The hero attacks automatically. Use the mouse or touch input to buy upgrades; clicking enemies also deals lightning damage. The creator recommends Max HP, Attack Speed and Attack Damage early in a run. This is the author’s advice, not a tested optimal build. Demo instructions
Choose what your run needs
- Attack: improves autoattacks.
- Defense: improves survival.
- Spells: supports mana and spell effects.
- Utility: includes rewards and the boss timer.
Use Manage Hero and Manage Spells for permanent improvements that carry across runs. Upgrade explanation
Before selecting Hell Mode
The creator’s 0.7.4 notes say Hell Mode requires a new run and defeat ends that run. Treat this as version-specific information. Official update
