Pixel Shooter

Pixel Shooter keeps its retro pixel-art presentation simple but escalates purely through wave density, later waves aren't smarter, just more numerous and faster, which shifts the actual skill test toward crowd control and positioning rather than precision aim alone.

Because upgrades unlock through survival rather than a fixed shop, prioritizing whichever upgrade increases your effective clear radius, wider spread or faster fire rate, tends to matter more against dense waves than a single high-damage upgrade that only handles one target at a time. Staying mobile and circling incoming waves rather than holding a fixed spot usually buys more time once enemy density outpaces what a stationary position can handle. Astro Survivors runs a similar wave-survival format with automatic firing instead of manual aim.
