I was set to write a more in-depth comment, but then I noticed that the computer cheats like a dog. Like worse than the AI on Civilization. "Oh, I see you're winning, here's five attack helicopters in a neat little train." FFFFFFFFF I AM SO MAD I CANNOT REVIEW
First of all, this is a pretty good game. I was strongly reminded of the [whatever] Maker series. But with less creepy influence. Overall though, it was sort of lacking in depth. A good game, but with some more work it would be great.
Second, hur dur battles are random. Bump your stats, people. It's not that hard.
I love simplistic game designs like this sometimes. It even manages to tell a little bit of a story other than 'YOU ARE ESCAPE MAN JUMP TO NOT DIE ON THINGS'.
