There is nothing quite like sharing a keyboard with a friend, laughing and yelling at each other as you try to beat a puzzle together. If you are looking for a fun two-player co-op game in your browser, Portal Adventures on Woko Games is a solid little pixel platformer worth checking out.
You and a friend control two blocky characters, one green, one blue. You have to work your way through layered stages (from level 0 to 3) packed with spikes, crawling bugs, and green gems. The main trick is using the colored portals to warp between different floors so you can grab all 36 gems and reach the exit in one piece.
Playing together sounds easy until someone misses a jump, lands on spikes, or steps into the wrong portal and resets the whole run. Having one person on WASD and the other on the arrow keys, shouting out warnings while trying to grab every last gem, gives it that classic, chaotic couch co-op feel.
Think you and your buddy have the teamwork to dodge every trap and clear every stage? Grab a friend, head over to Woko Games, share a keyboard, and see how far you can make it!
