Let me start with this: Awesome Game! Great Ideas.
The Beginning was very enjoyable, following the story did seem fun. But after a while, the maths don't seem to add up in a decent way. For instance: I just roll through worlds right now, the power of my Trimps vastly greater than any foes (just 1-hitting anything, really), I just get the weapon upgrades once in a while from the maps, whenever I get the chance to die, that is. Employed Trimps don't really have a purpose anymore, since I get way more resources from the world and other maps, and trainers+gyms now only block the tiniest fraction (Factor of a billion or more) of the enemy damage or even of my whole health. Also, since housing is way more expensive than buying new weapons my population of trimps doesn't rise fast enough to buy all the coordination upgrades. So to sum it all up great game, though it rapidly gets unbalanced past the first 5 or 6 worlds.
So I have to attack this enemy city if I happen to click on it by accident, apparently can't beat it and die. Unfortunately, the autosave overwrites the save, and the autosave puts me back in the enemy city, with no option but to fight them. Grrrrreat!
