Hello!
First of all thank you very much for good feedback. We are at knowledge of... this too floating behaviour ;] To be honest, the break should not be in this version, but we decide to leave it as is. We think it is too OP, and making the gameplay too easy.
Springs are lenght-limited. So you could have been too far from building. It can take some time before you get use to it, but it is, like you said, challenging someway :)
Hopefully you will enjoy our work even more! (Maybe there will be 'expanding' patch soon; bigger city, and few new features :) )
