## Getting Started Fireline Merge Defense is a high-octane tower defense game that blends strategic planning with the addictive mechanics of merging. Your core objective is simple yet challenging: protect the core from relentless waves of enemies while managing limited resources. You earn currency by defeating foes and merging identical units or items to unlock stronger defenses. The game features a vibrant, cartoonish art style and a catchy soundtrack that keeps the tension high. You can pause the game at any time to strategize, and your progress is automatically saved, allowing you to pick up exactly where you left off. ## Pro Tips To dominate the later waves, you must master the merge mechanic. Prioritize merging lower-tier units into their higher-tier counterparts immediately after spawning them; this maximizes your damage output early in each wave. Always keep an eye on the "merge count" limit for specific units and plan your resource allocation accordingly. If you have a few extra lives or boosters, use them during the first few waves to clear out enemies that are difficult to merge. Furthermore, don't forget to collect all scattered resources on the map, as they can be crucial for healing or upgrading defenses when you're low on health. Timing your merges to coincide with the arrival of enemy waves can turn the tide of battle, often resulting in massive chain reactions that wipe out entire groups of foes. ## Controls - **Mouse**: Click to spawn units or collect resources. - **Left Click**: Select a unit or resource to merge. - **Right Click**: Move the selected unit to a different location or merge it with another unit. - **Double Click**: Quick-select all units of the same type for efficient merging. - **Spacebar**: Pause the game. - **Tab**: Open the inventory or upgrade menu. - **Esc**: Close menus or quit the game.
