Ninja Rinseout

Ninja Rinseout was one of those games you'd find in the late 2000s, tucked away on a Flash game portal. It fit right in with the era's simple, fast-paced action titles. You played as a ninja, an agent sent to rescue a princess held somewhere in the area. The goal was straightforward: eliminate the opposition before they spotted you.

You control the ninja with the arrow keys, moving left and right and jumping with the up key. A distinctive mechanic lets you run up walls if you hit one during a jump; from there, pressing away from the wall performs a backflip. You press S to attack with your sword and down to duck, which also lets you hide in bushes to avoid detection. The game moves quickly, demanding precise timing to clear each area without being seen or taking too many attempts. It feels like a tense, fluid exercise in stealth and timing.
