First off, this is "nothing new or interesting". You control a couple of guys with your mouse to fight other guys. From that I took away a star because that is really *all* you do. There is no story, no advancement, no novel enemies, no upgrades. Then I took another half a star because you don't even need to control your warriors. I stopped at day 8 because you could just stand in the middle and wait. Until then even the archers alone, standing around without a player would have been enough! I also took away half a star because at first the game didn't advance to the second day, which seems to be a common occurrence.
In conclusion: if you want stars, make a real game. This is at most the beginning of one. Telling people where to run on an empty plane should not be your entire game!
