Bridge Builder Simulator

I just beat the entire game, 4 stages, 24 levels each. Each level gets progressively harder. The physics are accurate and it’s a good amount of challenge at the normal difficulty. You can’t change the difficulty because it costs money, but that’s the only thing in the game that is really off limits due to money. If you need a hint you can watch an ad and it will build around 20%-25% for you. The game is fair and isn’t unreasonable. The only thing I wish I could add would be a sandbox type mode, with unlimited money.
