Tips and tricks
- Learn the first thirty seconds perfectly. The opening is the same every time, so it should never be where you lose.
- Play in a quiet tab with nothing else running. Small frame drops cause missed timing that feels like bad luck but is not.
- Restart early. If a run starts badly, do not grind it out; a fresh attempt costs nothing and saves your focus.
- Look one step ahead of your character. Reacting to what is under you is too late; reacting to what is coming is exactly on time.
- Because this is a Arcade game, restart early when a run goes wrong instead of grinding out a poor score.
- Because this is a Adventure game, explore side paths early; adventure games hide their best upgrades away from the main route.
