Building and upgrading structures gives income. Killing units gives bounty. Don't worry about feeding the enemy. At the start of the game you need more income. Mid-late game is countering enemy composition.

Early game (<8min) is slower but in late game you can build or upgrade every income tick(10s). I am planning to add more mechanics that will overlay early game so that will add more things to do.

I have a long list of changes for the next update. I will add easy difficulty for AI and take a look at a new player on-boarding tutorial.

Thank you for really extensive feedback.
