Cat Bag: Merge Tower Defense

The rats have taken over the street. Time to arm the cats. Cat Bag is a merge tower defense game where you build a squad on a grid, fuse weapons into stronger ones, and hold the line against waves of rat mafia. MERGE TO POWER UP Drop two matching weapons on the same cell and they fuse into the next tier. Green, blue, purple, gold - four tiers, each hitting harder than the last. Push a weapon to the top and it earns the MAX badge. PLACEMENT IS EVERYTHING A weapon only fires if it sits next to a cat. Diagonals do not count. Every wave turns into a puzzle: where do the cats go, which guns do they reach, and what gets left cold on the board? EXPAND YOUR BOARD You start on a cramped 3x3 grid. Earn block pieces and grow it - more room means more weapons, more cats, more firepower. DAGGERS, PISTOLS, BATS Short-reach bruisers that hit like a truck. Pistols that pick off targets from a distance. Submachine guns that never stop chattering. Every weapon carries its own cooldown, range and attack speed to plan around. HOLD THE LINE Rats pour in from the right and charge your patrol car. Clear the wave to move on. Lose the car and the street is theirs. SHORT ROUNDS, REAL DECISIONS Set up, hit fight, watch it play out. A round is short enough for a coffee break and tight enough that one bad placement shows up in the result. Merge, place, defend. Easy to start, hard to master.
