城市塔防-City Tower Defence

Snowmen are attacking Shanghai, and you must hold the line on a battlefield that changes every run.This is a single-player roguelite tower defense game built around map variation, run-building, and defensive adaptation. In each run, the map generates a different identity, including base position, frontline structure, pressure lanes, and defensive space. You must read the terrain, place towers carefully, manage resources, and survive 30 waves of escalating enemy attacks.During a run, you will:

• Build and upgrade towers to create a defense suited to the current map
• Choose between-wave rewards to shape the direction of your build
• Use cards and upgrades to create synergies and strengthen your defenses
• Respond to changing pressure across lanes, enemy types, and wave pacing
• Decide whether to take on optional objectives for extra rewards
• Survive elite enemies and boss waves that can break an unprepared frontline

The core of the game is the interaction between random map structure and build decisions. Different maps change how you defend, where you invest resources, and how early or greedily you can scale. A build that works on one layout may need a completely different approach on another.Progression in each run is driven by constant trade-offs. You may need to reinforce a weak lane immediately, invest in long-term scaling, or risk taking optional objectives to gain more power later. As waves escalate, enemy pressure increases and small mistakes become harder to recover from.The current version includes the full core gameplay loop: randomized maps, map identity selection, between-wave reward choices, tower and card progression, optional objectives, and a complete 30-wave combat run.
