“To me, it's a pretty impressive first outing for a new developer entering what is one of the most complex genres in PC gaming—the kind of fiddly logic puzzler with a very specific niche theme.”
PC Gamer

“...a surprising and fun way to translate the process of making modular synth patches into cool logic puzzles—which is kind of what modular synthesis is all about in the first place.”

“...a brilliantly tactile puzzler that turns the tangle of cables and muddle of modular units into a challenging, Zachtronics-esque game of logic.”

Come hang out!
