Tips and tricks
- Aim for consistency before you aim for records. A steady run that avoids mistakes usually scores higher than a flashy one that ends early.
- Restart early. If a run starts badly, do not grind it out; a fresh attempt costs nothing and saves your focus.
- Combo systems reward patience: keep the chain alive with safe moves rather than reaching for risky bonuses.
- Take a short break after three or four failed runs. Arcade games punish tired eyes more than any other genre.
- Because this is a Adventure game, explore side paths early; adventure games hide their best upgrades away from the main route.
