5 stars: My one pet peeve about this game is that sometimes you don't know what you're doing when solving puzzles of this nature since upon arriving at the solution, you automatically finish the level. One way to counteract this is to allow us to MANUALLY check for solution instead of game telling us if we completed the level. Otherwise fantastic logic puzzle game, not too easy but quite challenging indeed.
5 stars: The puzzles are fun. Worth paying for no ads. But now that I have completed the levels, I wish that the endless mode were harder. I would love more complicated logic circuits with all the inputs true or false, To figure out the puzzle from base one. Or puzzles with feed back.
5 stars: One of the few truly engaging logic games, actually requires you to think through your desicions and punishes random button spamming. Wouldn't say no to more logic-gates (of course). I believe the star-lives system in endless-mode may need tweaking as it's currently very hard to die after a bunch of levels. Great game nonetheless!
4 stars: A simple puzzle game that engages the mind in a relaxing way. The challenge is mostly staying focused and avoiding mistakes. Not very difficult and the difficulty doesn't always scale linearly (some later levels are easier than earlier levels). Good aesthetics. Worth trying.
5 stars: It's very exciting game. I loved it at first sight! Every one can play and it helps to understand boolean logic. Thank you, developer, you made superb ...
