Warp Factory (tuxdb.com)

Unleash your inner engineer and build factories to produce objects of every shape and size! Use a powerful system of portals to reconfigure the very nature of space itself to conform to your desires!
Warp Factory is an automation puzzle game consisting of many varied challenges - produce intricate shapes one block at a time, build intelligent systems that process randomized input, carefully assemble strange pieces into larger segments.

Use portals to move objects from place to place - or to transform them by rotations and reflections:
Use welders to build big things from small ones:
Use pistons and sensors to push things around:
Use magnets to pick up tricky to reach items:

Invent the machinery to make use of the twisting geometry of portals and apply it to a collection of challenges designed to explore every facet of an unfamiliar world of factories.

Features

A unique physics engine, featuring welders, portals, pistons, sensors, magnets, and wires - and some more surprises here and there.
A campaign of 90+ individual levels.

Quality of Life and "Gravity" Update

Hello Warp engineers,

A new update has arrived, featuring many improvements to quality of life as well as some new puzzles!

Major Changes:
* Revamped wiring menu now highlights connected networks and can be opened during simulation.
* ...Now highlights network of connected wires.
* ...Wires can be deleted between specified points by holding Ctrl.
* ...Clicking and dragging while one node is selected can wire every node dragged over to the original one.
* Added a new chapter "Gravity" as well as a new level "Sculpture" to Assembly III

Minor Changes:
* The front faces of conveyors, sensors, and magnets can no longer be welded to. The side faces of piston arms also cannot be welded to.
* Various changes to modding:
* ...Added after_level_setup and before_level_setup callbacks in standard Lua setup.
* ...Wires and pins are properly copied by Lua.
* ...By default, checkers trigger disposal on the whole right side of their disposal region.
* ...Added an error screen in case level loading fails.
* ...Added a search path in Library folder of mod.
* ...Added a cursor to the console editor and allowed pasting to the console.
* Added "No Cross Welding" achievement to Antenna.
* Delete tool highlights cell it's pointed at.
* Hovering over a portal with no tool selected highlights its pair.
* Left clicking and dragging while having something selected now replaced the selection.
* Right clicking and dragging now deletes an area.
* Holding Ctrl while placing a single block also pins it in place.
* Holding Shift while placing a single block also welds it to all of its neighbors.
* Added a cursor to indicate unwiring.
* Added redo

Bug Fixes:
* Fixed a fatal error occurring when cutting a portal, undoing, then placing the cut component.
* Lua "print" only displays once now.
* Any pair of welders will now function. The left/right distinction has been removed.
* The unlock screen now shows a line break between a single chapter unlock and a single level unlock.
* Fixed various bugs about cut/undo not properly handling joints through portals.
* Disabled some assertions that caused random crashes.
* Orphaned PortalOuts only select together if they are welded together.
* Dragging with basic block placement tool now welds even existing neighbors together, as intended.
* Welds that are newly created can no longer pass through portals that would split them.
* The game's pointer for which level to reload to is deleted after it is used.
* Achievement notifications are only sent once.
* Made order of placement irrelevant to physical simulation on the half step.
* Pistons can be pasted on top of existing blocks without losing their arm.
* Fixed objects sometimes getting stuck in places where portals have repeatedly activated and deactivated in complex patterns.
* Fixed resizing's interaction on "Copycat".
* Fixed typo in description of "Memory".
* Fixed miscalculated height of text rendering.
