Jonathan Holmes (crait) recently gave us a shout to tell us that his challenging but fun top-down, tile based puzzler of ' Circuit Dude ' is on Steam and might be worth your time to give it a go and put your brain and skills to the test. Featuring 100 levels of crazy circuit chips and buttons and over 12 hours of gameplay, you must help Circuit Dude build his ultimate secret invention by plugging in chips, pushing blocks, stepping on switches, rotating walls and so much more!
