Brilliant Game! Hours of Gameplay!

This is a really awesome, and challenging game. It's not like one of those games with arbitrary criteria for winning. It gives you very detailed information on objectives and precise visualization of stresses. You can change the camera angles and speed up or slow down gameplay to really get granular with how you solve each design challenge. The graph that shows how your design compares to that of other players is a nice touch. I keep trying different designs just to be more economical. The developer gets extra kudos for making a game free of any up-sells. Worth every cent!

Great but needs some help

I love this game so much. It’s the perfect challenge puzzle game with realistic physics. The challenge of making your bridges work and stay under budget always has me thinking of ways I can do more with less. However my one and only complaint with the game is how heavy it runs the battery down. Just playing for 5-8 minutes knocks off 10% or more of my battery power. It’s been the top consumer of energy on my phone since downloading. It also causes my phone to get very hot as the demand on the phones performance is increased. If there’s an update that could improve the functionality of this games performance impact on my phone I’d give it 6 stars if I could. Until then due to the high impact on battery life my review will remain a 3.

Good game with a couple of severe design flaws

The problem is that you you can contract a hydraulic up to 50% (halving), with the opposite of this being expanding 100% (doubling). The game only allows you to expand a hydraulic 50%, meaning that two identical hydraulics starting in opposite configurations at full range of motion are impossible. This means I have to reengineer a second solution for what should be an identical second bridge in level 2-13

Either there needs to be the ability to expand a hydraulic 100%, or you need to be able to set a hydraulic to start in a different simulated state when the level is run.

The first solution would work and be much less invasive a change than adding starting states for hydraulics, but that leads to the second design flaw. In order to create something in a different state, you still have to completely redraw it. There really should be a way to move and rotate groups of joints in order to translate existing designs. The lack of this ability means redrawing constantly.

3 stars because the issues mentioned seriously impede on the fun aspects of gameplay
