When I was a kid, I loved that old predecessor of this game. So I decided to pick it as soon as it is on a sale (basically because I doubted the quality of the game. The mechanics are old and trusted but still... I was affraid to see a soulless clone). Happily, this one brought me a crazy level of excitement and (even!) laughings!
The game is awesome and catchy. Once I laucnhed it to test for a while, I realised I have played like 80 minutes or something. And Contraption Maker didn't bore me at all. The missions are set in a very clever way, so each one is a bit harder then the previous, but not too much. You actually learn to play it step by step.
The puzzles are interesting and (the main thing!) really really different. I guess their puzzle designer is a nice guy with a good sense of humor. Besided, every puzzle has some kind of a plot, so you even start to sympathyse some characters (My fav is Waldo, what a gorgeous cat!).
The game is simple and exciting, it is very light and kind, reminds me the most childish looney tunes cartoons. The music is awesome, and the controls are very intuitive. The only thing I noticed is a small little difference between designs of some elements and characters, but that's not a problem at all, just noticed.
I've picked it for 0.99 on a sale and even recieved an extra copy to give some of my friends. I believe it would be an awesome present.
Hardly recommended. If you are lucky to see it on a huge sale, take it without any doubt. I am not a fan of puzzle games, but this one is awesome even for people like me.
