Game Overview
Super Marco is one of those old-school Flash games that just gets chaotic fun. You start off with this ridiculous shotgun-machine gun hybrid—like, who thought that was a good idea? (It was.) Bowser’s minions come at you in waves, from these weird caterpillar things that crawl along the ceiling to Shy Guys that dive-bomb you out of nowhere. And Rex? Yeah, he’s still a pain.
At first, I kept forgetting about the shield (hit 'H' when things get messy), but once I got the hang of switching between guns, bombs, and that trusty knife for close calls, it clicked. The weapons feel stupidly overpowered in the best way. You’ll probably die a lot early on, but in that "one more try" kind of way. Just don’t get cornered by the caterpillars—trust me on that.
