Secret Agent H5

Every level hands you a silenced pistol, a few gadgets, and a room full of guards—your job is to kill every last one without raising the alarm.

I spent an embarrassing amount of time on level 14 because I kept shooting the wrong guard first. Secret Agent H5 is the kind of puzzle that makes you feel cleverer than you actually are. You get a top-down room, a handful of enemies, and a limited set of tools—a gun that fires one bullet, a block you can push, maybe a wall you can phase through. The trick is that enemies only die when you hit them in the right order or from the right angle. The controls are dead simple: click to aim, click again to fire, or drag to place a gadget. But every level is a little logic knot. One puzzle has three guards in a triangle; if you shoot the one in the back, the other two turn around. If you fire at the wall, the bullet ricochets and takes out the guy behind the crate. I didn't believe the angle would work until the guard dropped and the level cleared. That's the payoff. It's not a long game, but it doesn't need to be. The difficulty ramps up quickly, and some of the later levels demand genuine trial and error. You'll restart a lot—not because it's unfair, but because you missed one detail. If you like puzzles that respect your time and make you feel like a spy, this one's an easy afternoon.

You take on the role of a secret agent whose objective is to destroy enemies.

Plan your first move before clicking anything—guards react to noise and line of sight.
