Dude...
I'm giving you a seven because I like the concept and the execution, and I feel that marking you down too low because of my own frustrations isn't entirely fair. Nonetheless, I cannot figure this game out for the life of me. I barely passed the first level on sandbox mode (after some experimentation), but I don't understand what I'm supposed to do to make the bridge stay together. My suggestion? Expand the freakin' instructions, man! Maybe I suck at physics/architecture/etc., but the vague advice of "triangles work best" didn't help at all. Cause let me tell you, I made triangles. Oh, did I make triangles...maybe you could have a picture of a successful bridge, so that we have some models to work with? I dunno. But as it stands this game is too difficult for my feeble mind to figure out AND enjoy at the same time.
