Yep, this is not the final control and also not the final game, just a prototype. The building of rails will be changed as the rails popup will be disabled and you will see the possible routes instantly as you build one. You click on the desired one, and you will se the next ones in that moment, etc... So you have to hold down only once and then just click/tapping on the right ones.
Amm... yeah I'ts maybe sounds a bit too complex, but belive me, it will be cool!
Also there will be tons of improvments and quality of life updates. This version was about to make it work, now comes the fun part of the development :)
