Tips and tricks
- 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.
- 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".
- Keep moving. Standing still is the most common way to lose an action round, because the game is designed to punish hesitation.
- 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.
- Because this is a Strategy game, economy first, power later.
- Because this is a Tower Defense game, build at corners where the path doubles back so towers get two passes at every enemy.
