- The core idea is sound enough.
- Not being about to move the camera around the field makes it difficult to place structures and units.
- A visible grid would be nice so I can see where I can and can't place things.
- A visible line indicating the enemies path though would be useful
- More resources or less expensive structures would be appreciated. I couldn't finish a single level because I couldn't build enough of a castle to slow them down or but enough units to damage them.
