The idea is very problem I found was that if you solved the level, you automaticaly had 3 stars, I never had a "how the hell do I get to that star" moment. I'm sure there is a way to add challenge for those who are looking for some.
Reviews for "Screw the Nut 3"
I think all physics-based puzzle games went decreasing difficulty and fun from 'build your own tracks' to 'find the obstacle'. These types of puzzle are just like COD, nothing changes from the previous game.
It is a ok game, not too challenging. Would've been nicer if there was a way to finish levels without getting all three stars. I was expecting I'd have to work to get all three at first but it's either you win them all or you fail the level
Not everyone thinks of mechanical work when you hear, "Screw the Nut." Just saying. But I though the game was okay... I guess.
I felt the game-play itself lacks in originality it's probably one of many "physics" based puzzle flash games I've played just repainted and renamed. I also felt the difficulty in regards to the game was rather easy rather although I am not too sure about the intended audience but generally while it has a lot of different features introduced to you it's not used well and almost feels like each level is a "tutorial" level. I give this a two because I enjoyed the charming art but that is about it.
