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!

Would like a refund

I am only 14 and I thought this game was going to be good but instead it was crappy.
The game controls on the IPhone is awful and has a 1in5 chances for it actually working correctly and the way I want it to work. I was trying to move the screen but instead I had added lots of wood stabilizers when I didn’t want that so I had to redo everything by deleting the whole bridge and restarting which was hard because I had forgotten the way the bridge had looked in the first place. When placing things down it was hard because the items would snap weirdly and then I would have to go back and fix it all by using another tool which was time consuming and made me frustrated that it was taking long.
I had asked for a refund but I didn’t qualify so I have a game that has bad controls and is very frustrating to play. Apple had said I didn’t qualify even though I had wrote about the controls and the sandbox but they ignored me, I feel like Apple has given up and is now just in it for the money which is annoying since we are to rely on them for help, refunds and recommendations. I am not trying to diss Apple in any way this is just my opinion and I could be wrong so you don’t have to believe me.

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.
