Due to limited time: The game may lack proper instruction. As such, allow me to assist:
Escape from the Game Screen will close the game.
If you select Unit 1, you will receive the unit: Press Spacebar to let it begin Patrol.
Unit 2 and Unit 3 are placed units, which means after clicking on one of them, you will then click on a non-roaded area to spawn them. Their radius are visible, but place carefully.
A 'day' lasts 3 minutes, but this can be sped up using the arrow button at the bottom right, allowing you to increase the pace of time by up to *3.
You can modify the difficulty by reducing the timer to spawn enemies (red dots) or villagers (blue dots).
The submission is not fully featured, as the population value is not set, as intended: which was to be based upon villagers successfully making it across with their goods. Currency also does not adjust per round. Each round restarts from the base values. I would recommend trying to use the base 1000 gold to most successfully defend from an ever increasing difficulty.
Unit 1 - Patrol costs 100 gold.
Unit 2 - Vanguard costs 300 gold.
Unit 3 - Archer Tower costs 200 gold.
