Fixing Errors In Lag And Issues Merge Cats: Tower Defense

Cat tower defense, with a merge twist. Merge two matching cats into one stronger cat, line your lanes with them, and defend the wall against endless waves of enemies.

Merge Cats Defender is a lane tower defense game built around one simple move: drag a cat onto a matching cat and it becomes the next tier. Fifteen tiers, five lanes, and a wall that will not hold on its own.

HOW TO PLAY
- Buy a cat and drop it into any of the five lanes.
- Drag one cat onto a matching cat to merge and shoot harder.
- Every tier hits for more, fires faster, and reaches further down the lane.
- Kills pay coins. Spend them mid-battle on more cats or on wall repairs.
- Sell a cat you have outgrown and get coins back.
- Hold the wall, clear the wave, beat the boss, push your record.

FEATURES
- Merge tower defense: 15 cat tiers, each a real jump in damage and range
- Five-lane battlefield: choose the lane to stack and the lane to gamble
- Boss fight every fifth wave, with heavy armour and heavy hits
- Endless waves that climb in count, speed and health
- Five battle areas to fight through
- Permanent upgrades: level every cat tier so your next run starts stronger
- Four boosters: Spike Trap, TNT Barrel, Boxer Cat and Help Friend
- Repair the wall mid-fight and buy yourself one more wave
- A best-wave record that is always one run away from falling
- Landscape play in short sessions, built for one hand
