this is probably the only idle game i've ever played where i actually have to think about what i'm doing, how im investing my money, research, etc. i think this is why it's absolutely brilliant, making something so mindless and simple into a sort of puzzle game that requires ingenuity and problem solving skills (as well as skills in arithmetics xD)
more enemies... PLEASE! and not in the quantity... i believe most will agree that the enemies are too few in type... there are about 7 types and they repeat constantly with a slight increase in hp and damage i guess, but other than that they get really stale after say 5th sector on epic... playing the 3rd ship is way too easy just run away and fire backwards after you get far enough to not get shot anymore and you win... it just gets boring at that point.
hotkeys for abilities, choices should matter more than a place on the statue at the end, farmers healing ability is way too powerful, too many parts of the plot end unexplained (young witch, who the hell is the clown and why the stupid adviser was trying to break all reconciliation attempts) good game, 4/5 just because there's almost no use for all the other troops except for the farmers
i wish the enemies would be the souls of other players - their copy with the same equipment after they died. it would be really fun to see how far others got and what equipment they had, the bosses at 5, 10, 15 etc. levels would be top players or something.
