Tips and tricks
- Use short practice sessions. Ten focused minutes will improve your timing far more than an hour of frustrated retries.
- 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".
- Learn the enemy or obstacle patterns before you try to go fast — most action games repeat a handful of behaviours, and once you recognise them the game slows down in your head.
- Keep moving. Standing still is the most common way to lose an action round, because the game is designed to punish hesitation.
- Because this is a Zombie game, never let yourself get surrounded — always keep an exit behind you.
