Planet Invasion

Waves of alien ships pour across the screen, and your only job in Planet Invasion is to make sure none of them survive long enough to matter. Scattered throughout the chaos are upgrade pickups — weapons, shields, firepower boosts — and grabbing the right ones at the right moment separates a decent run from a great one.

The retro pixel aesthetic gives the whole thing a satisfying crunch, explosions blooming in bright bursts against the black void. Enemy formations grow more aggressive the longer you last, and the pressure builds steadily rather than spiking all at once.

Score chasing is the real hook here. Every pickup multiplies your potential, and learning which upgrades chain well together adds a layer of thinking beneath the shooting. Short sessions or long ones — both work equally well.
