What are the requirements to achieve 2 or more stars on a level in Empire Defense 2? I've been looking but can't find anything. I've tried all sorts of things, but I get nothing more than 1 star as a result.
I tried the following in different combinations
- end with 3000 gold
- using only single unit
- using all available units
- end with general full health
- not using any path moves
- using all path moves
- strategic placement of units and path
- upgraded all units before adding new ones
- bought new units and another spot for them
- end each round with spare time
