How do you win that level. You don't have the time to save the people with fuel, and get fuel enough to get past the obstacles, that you have to remove with cthe crane. Hvae tried seceral times, and yes I have looked at the guide for that level.

i believe someone else asked the same question in german but did not get any replies so i am trying it myself now, how do i get the "Avia Mail - For receiving resources by plane" achievement? I have finished the entire game + bonus levels and have not received it; not in the game achievements or Steam achievements. Is it bugged or am i missing something?...

Where do I find the ingredients for the lab?

I tried several times but for me it´s way to hard to complete level 18. You have to keep the fire up and running for 100 wood (I can do that 3 times). In the meantime you have to gather enough money to rescue the people and clear the way to the doctor. I am running out of time,every try.... Is is even possible to finish that level?...

I’ll buy if the achievements are Steam achievements! Thanks in advance.
