You can slow it down using the - key (+ to speed up)and set the default speed in the options. That makes a huge difference.
The most important tips:
- build a forge immediately
- seize other building patches, especially recruitment platforms next.
- start build an army, and send it to that fortification that the enemy will attack first (but keep enough recruits to be able to dragon transform)
- try to avoid major confrontation until you can transfor and help your troops out.
- Once you have two ro three recruitment citadels, you can build a larger army. Assign a sizable queue to each forge/factory, set a gathering point, then you can spend time as a dragon, while your army gets constant reinforcements. Once you feel ready gaterh your army under your dragon and head out to conquer.
Served me well through the first battles.
