A logic gate puzzle game where you use a range of gates and other stuff to transform inputs into outputs. Starts out simple, but the second half gets tough, especially if you go for score. If only the logic gates used the real logic gate symbols rather than (mostly) squares with text or symbols. That'd make drawing out diagrams easier, if nothing else (the game doesn't save your layouts, so I ended up taking my own notes, which is also fun). Overall, this game reminds me of increpare's fantastic little puzzler Alien Keymap, though less inscrutable.
My progress: achieved the best module counts in all levels except level 6 (where I have 8 modules) and level 9 (where I have 13)
