Robot Unlock
Solve puzzles with a few instructions and synchronized threads
Robot Unlock is an open-ended programming puzzle game in the style of Zachtronics. Each of its 75+ levels gives you a small set of instructions and a tight space, and you write a program that solves the challenge. Later levels add several threads that you must time and synchronise.

About Robot Unlock
It trains low-level thinking and concurrency. You can optimise for speed, instruction count or space, and a debugger with breakpoints lets you step forward and backward. It suits intermediate players who liked TIS-100 or SIC-1.
It is free on Steam for desktop. You can also build levels and share them with other players.
