About Cosmic Courier: Trapped in Limbo

Launching you straight into the retro-futuristic depths of space, Cosmic Courier: Trapped in Limbo delivers a uniquely challenging indie adventure crafted by a passionate team of developers. Built in GBStudio and available seamlessly via browser, this free HTML5 game fuses nostalgic Game Boy vibes with a compelling detective mystery. You step into the space-boots of a cosmic courier caught in a surreal limbo: someone has ordered a highly suspicious package, but the sender remains a mystery. Your much-anticipated days off have been interrupted — and until you crack the case, cosmic relaxation will have to wait!

Fans of pixel art and inventive storytelling will be instantly hooked by the game’s gorgeously minimal visuals, reminiscent of 8-bit favorites but pulsing with smart modern design. Each scene brims with quirky NPCs, secret clues, and mind-bending puzzles, all wrapped in an atmospheric chiptune soundtrack composed by both Matte Lindsay and Jack Thompson. The tight, focused story—expertly written for maximum intrigue—will appeal to sleuths and speedrunners alike.

With its hard difficulty, Cosmic Courier isn’t here to hold your hand. Every room is packed with clever traps, tricky dialogue sequences, and hidden objects begging for discovery. Your choices matter: interrogate NPCs, analyze evidence, and track down the real culprit behind the cosmic con. However, you’ll need more than just quick reflexes; your wits will be your most valuable tool as you piece together fragments of the story and navigate a web of intergalactic suspicion.

Playable directly from your browser or on mobile, Cosmic Courier: Trapped in Limbo is perfect for gaming anytime, anywhere. Whether you’re a seasoned puzzle pro searching for your next obsession or an indie fan craving something fresh, this title offers both style and substance. Built for the Goblin Game Jam February 2021, it showcases an impressive blend of creativity and technical skill—and with replayability that keeps you coming back for more, your cosmic shift is just getting started. Dive in and discover if you have what it takes to break free from limbo and finally claim your well-deserved rest!

How to Play

Getting started in Cosmic Courier: Trapped in Limbo is as easy as visiting your browser or mobile, no installation needed! As the space courier, your objective is to identify who ordered the mysterious package by navigating a labyrinthine space station and interrogating quirky suspects. Use your arrow keys (or swipe controls on mobile) to move through vibrant pixel-art rooms. Interact with objects and NPCs by pressing the action button (typically Z or Spacebar; tap the screen for touch devices).

Pay close attention to dialogue and environmental details—clues may be hidden in conversations or background items. Progress by piecing together evidence, solving environmental puzzles, and unlocking access to new areas. The game rewards observation and lateral thinking, so don’t rush!

If you feel stuck, revisit previous rooms—characters might react differently after key events, and new options can appear. Every decision counts toward uncovering the real culprit, and some secrets are only revealed after persistent questioning or re-examining evidence. Save your progress regularly if the option is available, and don’t be afraid to restart with a fresh perspective for alternate endings or hidden content.
