Fun game in the all too rare CCG/RTS design space.
Devising new strategies as your collection expands is the backbone game mechanic, and it works well.
The "dialogue" is funny and rather charming.
You get to play several missions for free before having to decide whether or not to pay to continue. The 2nd and 3rd chapters can be bundled for $4.00. Aside from this, there is no IAP. Its a very ethical and fair business model.
Buy it!!
