Hard Chip

Here is an excerpt from Hard Chip's Steam description:

Step into the shoes of 'new_user', an engineer tasked with the monumental challenge of repairing machines to escape from an unknown location. Your tool? The fundamental building blocks of digital logic: complementary transistors.

BUILD YOUR OWN PARTS

Begin with the basics of electronic components, creating gates out of complementary transistors. Learn the art of electronic design as you progress from simple NAND and NOR gates to complex circuits capable of performing intricate tasks.

ASSEMBLE THEM

Combine your gates into larger, more sophisticated parts. Each assembly is a puzzle, demanding not just intelligence but creativity, planning, and foresight.

OPTIMIZE

Optimize your designs for efficiency and space, pushing the limits of your engineering prowess.
