Tips and tricks
- When you die, note exactly what killed you. The answer is usually one specific pattern, and fixing that one thing is worth more than "trying harder".
- Watch the edges of the screen, not just your character. New threats almost always enter from the sides or the top, and spotting them early gives you a full second of extra time.
- Do not chase every bonus. Collectibles placed near danger are a trade-off the designer set for you; take them only when your position is safe.
- Use short practice sessions. Ten focused minutes will improve your timing far more than an hour of frustrated retries.
- Because this is a Action game, keep moving.
