I really love this game and spend time collecting DNA.
BUT! I think you have sat the goals to high. It forces me as a player to buy all the time to develop.
For exampel campaining omg i have to raise my dinos to continue forward.
Now im sitting here, no green one and no coins.
I cant pay both for the came/month and 50000 to be able to play a campain.
Then the supply drops is sat on limitid amount.
Omg! Now i cant do anything for days. The sum to lvl is not ok. The system needs to shape up
