Many thanks for your feedback!
You are right: The tutorial is very difficult at the end. (Probably a bit too hard/unfair.) To win you have to constanty build gatherers and as soon as the buggy factory is available build one. Then start producing buggys and buld a second buggy factory. That should do the trick.
I will overwork the tutorial for the next update to make it less frustrating...
I never got feedback on the tutorial before, most testers directly jump into the matches vs AI. Those are much less difficult than the tutorial.
Great feedback!
