Pixel Grid Guardians

Pixel Grid Guardians: Numbers Defense
The retro pixel arcade strategy game that combines addictive number merging with the tactical depth of tower defense — a grid-based merge puzzle game wrapped in satisfying pixel art.

Command a fleet of pixel spaceships to defend your grid against waves of alien invaders. Deploy ships, merge identical ones to double their power, and watch them blast enemies with fiery projectiles. A level 1 + level 1 becomes a level 2. Two level 2s become a level 4. The stronger your ships, the more damage they deal — but the aliens get tougher every wave, so plan your merges carefully.

How to Play:
Tap to deploy your next ship on the defense grid
Match identical ships to merge them into more powerful vessels
Ships automatically fire at aliens in their row each turn

Survive all rounds to earn up to 3 stars per level
