Hello,
I've added the 4th tutorial campaign, focused on an introduction to sequential circuits. It covers latches, D flip-flops, and registers. The final level is a mini Nand Processing Unit, which some of you might enjoy. It's a minimal CPU with only 3 operations: NAND, LOAD, and MOV, and it runs an AND gate program steamhappy. The idea is to develop it further in future campaigns, adding addressing and more instructions.
Also:
Fixed the achievements code: campaign completions now unlock Steam achievements.
Fixed a bug/imprecision in the delay/energy calculation for upper layers.
Added a "See time stats" tool in the simulation options to display the delay of each pixel.
Added an option to display the game in "Always On Top" mode.
Thanks for playing! If you're enjoying the game and haven't reviewed it yet, please consider leaving a review—it really helps with visibility.
