Hey, thanks for the feedback.
"best strategy is slowly building up resources before expanding too far" - exactly. And it fits the jam's theme as well. You need to scale before you can handle bigger rushes.
I wanted to make "Sap" more valuable, so you will prepare for battles first, but it didn't work that well. But I already have some thoughts on better balance. Like adding obstracles, more fighting strategies and so on. Will defenetly work on it post jam.
