That's right, it's me, the over-builder.
I don't know anything about building bridges, in or out of games, so I trust that all the three star goals are very achievable for others. I was happy enough to get to the top. I mean... to make a connection.
Having the little guys clambering all over the framework while it was being constructed made things a bit more difficult than they needed to be, I'm sure that was the point of doing it that way. I'm guessing it was quite a bit of work to get the physics to behave how you wanted.
The addition of balloons and anchors in later levels did give a sense of keeping things fresh and interesting. I'm not totally sure they were needed, though. I threw some in for the sake of it, they probably made things easier. Actually, I thought the anchor was a grappling hook the first time I saw it, and tossed all my work off a cliff.
The art's very nicely done, both in and out of cutscenes. The music is nicely chill, a bit repetitive since it's looped through from the tutorial to the end. The sound effects are a bit sparse, but I'm not really sure where you'd use them outside of the places they were included (though the entering tent noise does get interrupted by more and more climbers barrelling in at nearly the same time.)
[Edit] - I forgot to mention, you have a typo on your page. "Stroy" instead of Story
