great game but i think it needs a few improvements...
sugestions:
1. partial refund for selling
2. Start with only 3 or 4 slots but gain slots over time with a higher maximum
3. little bit more balance/more units
4. stronger possible army [more slots or higher [bought] levels]
5. harder story missions, optinals give more cash
that's all
