Hyperspace Garbage Collection Unblocked

Hyperspace Garbage Collection casts you as a round little janitor robot with an expressive face, floating through dark caves where warp holes keep spitting out square chunks of trash. Some chunks are blue matter, some are red antimatter, and you can switch between the two yourself. The puzzle is getting the right color onto the right switch before it fades away. Raymond Zhou made it for the GitHub Game Off jam in 2013. This unblocked copy keeps all four chambers, and you can play it with a keyboard or a finger.

Matter, Antimatter and Doors

Hit start and fly around with the keys or by dragging. The robot drifts with a bit of momentum and shoves any trash that matches its current color.

Every chamber has at least one round switch. A wire runs from the switch to a door. When trash of the switch’s color touches it, the piece locks in place and the switch glows. Light every switch on a door’s wire and the door slides open.

Color decides almost everything else:

• Matter and antimatter trash destroy each other on contact.
• If the robot rams trash of the opposite color, that piece blows up with a screen shake.
• Lasers slice through trash of their own color and ignore the other.
• Tractor beams carry loose pieces along a fixed track.
• Every piece of trash fades after a few seconds if it never reaches a switch.

The first room has no color button at all. From the second on, you can swap modes, and the final rooms need one piece of each color, so you switch partway through a push.

Pushing Trash Like a Pro

Start each attempt at the warp hole, not in the middle of the room. Trash has a short life, so meeting a fresh piece the moment it appears gives you the most time.

Glance at your robot’s ring before you charge. If its color does not match the piece, you will pass straight through or blow it up instead of moving it.

Use destruction on purpose. Stray pieces of the wrong color clogging your path are easy to clear: switch modes, ram them, switch back.

Let the machinery work. A gentle nudge into a tractor beam often carries trash most of the way to the switch, leaving you only a short final push.

Treat lasers as color filters. Route red trash around a red laser and through a blue one.

If the game stutters on an older laptop or phone, open the gear menu and turn off the background, glow, gradients, explosions or trail.

Worth a Look If

You like small, handmade physics puzzles with a clear goal and no punishing fail state, this is a quick and charming one. It plays well on touch screens, which is not true of many jam games. For more floaty physics, try Gravity Golf or land carefully in Moon Lander.
