A real conspirising game, 5/5. The real challenging levels are however the last two levels, took me for about 2hours. Many levels are really full of fun, and hints are very accurate, not too much to spoil and not too little so that would render it useless.
The best leader is the archer. It seems like healer's great at the start of the game, but then the healer's dps is too low. If your aoe dps is high enough in fact teammates won't be hurted often, and the hp bottle ability of archer will help more. with the protragonist+archer+gunner, mass enemy will be cleared in seconds.
Can you provide me the screen shot ?
