I've seen this type of game before and although it won't change the world I thought it might stretch my brain and pass some time so I downloaded the trial. Not sure if I'm the world's worst bridge builder or if it's nigh on impossible to build a stable enough bridge within the lower budget to get the crown. It's a challenge to just build a bridge that won't fall down. There's a tutorial introduction to most levels but they don't seem to be relevant to the next bridge you have to build. EG roof tutorial leads onto a level where the roof option is greyed out so you can't build one. A roof was available for the previous level and was needed but it was only by trial and error that I used it. Given that you only have a finite budget anyway some bridges are impossible to build. The tutorial says you can always ask for a hint and helpfully highlighted a button I didn't have and so I couldn't get help even when I wanted it. This could have been a good game but wasn't. A combination of impossible tasks and what seem like glitches, it's an exercise in frustration. I won't be getting this game even with a credit.
