Red and Blue Adventure

Grab a friend and put your teamwork to the test—Red uses WASD, Blue uses the arrows, and both of you need to snag every diamond before that door opens.

Red and Blue Adventure is the kind of co-op platformer that turns "just one more level" into a two-hour argument about who moved the wrong way at the wrong time. You control both characters—or one each if you've got a friend—using WASD for Red and the arrow keys for Blue. The goal is simple: collect all the diamonds scattered around each stage, then get both characters through the exit door. Sounds easy until you realize those diamonds are often tucked on high ledges or across gaps that force you to time jumps carefully. I kept messing up the double jump at first—tap the jump key again in mid-air and you get a little extra height. It's the kind of mechanic that feels unnecessary until you're one diamond short and the only way up is a ledge just out of reach. Red and Blue both get that double jump, so don't be shy about using it to correct bad landings. The real challenge isn't the platforming itself; it's syncing two characters who move at the same speed but often need to take different paths to gather diamonds before regrouping at the door. Since both characters have to reach the exit, you can't just leave one standing at the start. You'll hop back and forth, clearing a route for Red, then switching to Blue to grab the gems on the other side. It's perfect for two players on one keyboard—WASD and arrows sit side by side naturally—but single-player is just as valid if you like juggling two control schemes. Don't expect a story or power-ups; this is lean, uncluttered co-op jumping that respects your time but still finds ways to make you fail a jump three times before it clicks.

*WASD + Arrow Keys! *collect diamonds! reach the door! *Double Jump Available

Assign Red to the player who's better at precise jumps—WASD feels tighter for some reason. Double jump resets when you land, but not when you fall off a ledge; time it before you're over the gap. Don't bother splitting up too early. Clear diamonds with one character, then bring the other through. If you're solo, park Blue on a safe platform and scout ahead with Red—just remember Blue still needs those gems. Watch the door; it stays locked until every diamond is collected, so count them before you waste a trip. Use both characters' double jumps to skip small platforms entirely; some diamonds are easier to grab from above.
