Strategy Tips

Energy is everything - More workers = more energy = more units
Expand early - Spawn workers continuously until you have 5-8
Build towers - They auto-attack enemies within range 10
Mix units - 1 soldier per 3-4 workers for defense
Build storage - When spawn is full, store excess energy
Repair structures - Workers can repair damaged buildings
