Sync Simple is a tunnel shooter that comes with a basic level progression system, boss fights, and upgrades tied to your ship's capability to take damage. The level changes whenever you eliminate twenty-four aliens in the current area, and though the game starts out easy the enemies will eventually start to weave around and shoot back at you with their own weapons.

There are collectibles that upgrade your firepower, but if you get hit the guns will be weakened gradually until you're left with a single shot weapon. A collision with an invader or their projectile while in this state, and the ship explodes thus ending your mission abruptly.

Up to three power-up items can be amassed, and you will definitely need to hoard as many as you can get your hands on if you plan to survive longer than a minute on one life. Download Sync from here. (Windows, 2.05MB)
