I was looking for an electronics building kit or tutorial and ran across this game. It sounded interesting, so I downloaded it. Literally 4 minutes later, I completed it. It has 4 levels, and no more than 3 pieces are used (out of 4) on each level, making even trial and error easy. I’d love to see a fleshed out version of this with many more levels. At least I didn’t see any ads that may interfere with this short experience.
