Navvy app for iPhone and iPad

In Navvy you carefully place pieces of the rail track. You are highly advised to avoid all obstacles along the way, such as shovels, TNT, abandoned mining cars, crates, rocks and cacti, because if you hit one of these it is Game Over! Not only that, but you are running against the clock, which starts ticking faster with each level. Obviously, the railroad company is exploiting human labor.

But wait, what is that... Right there, on the ground... A flask? A flask of water? Praise the Lord as this will slow the clock a bit, so you could rest!

If only there was a way to jump over some obstacles, or even destroy them... However, this task would require springs or a gun...
