Somebody has to tidy up space, and today it's a round little robot with a face. Trash blocks pour out of glowing warp holes, and your job is to herd the right ones onto switches that open the way forward.
Hyperspace Garbage Collection unblocked was built by Raymond Zhou for the GitHub Game Off 2013 jam. It is a calm physics puzzle with a color twist: every piece of trash is either blue matter or red antimatter.
How to play Hyperspace Garbage Collection
After you press start, use the keys or a finger drag to steer. The robot floats freely and can only push trash that matches its own color. Bump trash of the other color and that piece blows up.
Each chamber has round switches wired to an exit door. Push trash of the switch's color onto it and the switch grabs the piece and lights up. Light every switch tied to a door and the door slides open.
Colors rule everything else too. When blue and red trash meet, both are wiped out. Laser beams destroy trash that shares their color but let the other color drift through. Tractor beams haul loose blocks along fixed lanes, and every block fades away if it sits around too long. From the second chamber on, Space or the on-screen button flips you between colors.

Tips
- Check your ring first. The color around the robot tells you which trash you can move right now.
- Clear the path by switching. Flip to the opposite color and ram any stray pieces that block your push.
- Ride the tractor beams. Nudge a piece into a beam and let it do most of the hauling.
- Steer around same-color lasers. A red beam wipes out red trash, so guide red pieces past the end of it.
- Catch trash fresh. Pieces don't last long, so grab each one as it leaves the warp hole and head for the switch without detours.
- Lighten the graphics if it stutters. The gear menu has toggles for glow, trails, explosions and more.
Hyperspace Garbage Collection questions
Can I die or run out of lives?
Never. The robot has no health bar and the game has no fail screen. Beams pass harmlessly through it, and ramming the wrong color only wrecks that one block.
Why can't I switch colors in the first room?
The opening chamber only teaches movement, so the color button is hidden. It appears from the second chamber on.
Is there sound?
No. This copy plays silently, since one sound file with an unclear source was removed. Levels and gameplay are unchanged.
Does it work on a phone?
Yes. Drag to steer and tap the color button. Turning the phone sideways gives the small play area more room.
