Mega Man Polarity is one of those classic Flash games that feels like it should've been an official NES title. You jump in as the blue bomber, blasting through robot masters with tight controls—just like the old days. The twist here? A polarity shield you toggle with Shift, flipping between red and blue to absorb matching enemy shots. Mess up the timing, though, and you’re eating damage.

First few minutes are pure nostalgia: running, jumping, charging your buster (hold Space for a satisfyingly chunky shot). The levels aren’t just rehashes—they actually play with the polarity mechanic, forcing you to swap shields mid-air or risk getting shredded. Feels like someone took Mega Man 2’s vibe and cranked up the reflexes needed. Arrow keys handle movement, mouse clicks through menus—no surprises there.

Honestly, the shield gimmick makes boss fights way more tense. You’ll catch yourself hesitating between swaps when a screen-filling attack comes your way. Dr. Wily would approve.
