Update 1.2 of "Cargo Company" is now available, with tunnels, improvements and bug fixes.
Details here:

- Tunnels You can now place tunnels in the game. Both railway tunnels and road tunnels are possible, on earth, the moon, mars and all other planets. Tunnels behave a bit different than bridges and can for example be stacked on top of each other. Tunnel entries and exits need to be placed at straight upward slopes, and a quite a bit more expensive than for example streets. This now opens a lot new possibilities in the game, and I hope you have fun with this new feature. Please note: Although tunnels have been thoroughly tested, there still might be bugs in edge cases. If you discover a problem, please report it!
- Productivity change and tooltip
Productivity increases have been adjusted slightly for some industries.
Also, there is now a hint as tooltip over the productivity display of industry buildings, showing the exact current productivity value and giving a hint how you can influence this.
- Town growth adjusted If you don't expand your transportation capabilities in the area of a town, large towns will now continue to grow a bit regardless, making the game a bit more realistic and fun to play.
- Fixed a small bug causing sound ouput to stutter in the first seconds of the game on some systems
- Other smaller improvements here and there
Thanks for all the feedback so far! Hope you like this update!
