I give it 1 start because of the graphics and music + the coding. I guess the point of this game is to make the players addicted which i can see it really succeeds to do but doesn't work on me tho. You get a "+" from me on that one too. But in a game where you don't have to do anything is not really a game in my opinion, meanwhile i'm writing this i can hear monsters getting killed without me doing anything. Is that how games now a days are? you don't have to do anything?
I'm a developer myself, I can't see how this could have been fun to make, i doubt you were having fun or at least you got bored really fast but saw the opportunity to earn money. It was a smart move of you. Tho some things you could have done better but I guess this game is only made for people that likes to do as less things as possible in their lifes so it's not needed to change these things i will say but still, I noticed you don't even have to click on the monters to kill them? You can click in the air and still kill them? You don't even have to collect the gold.
People are getting lazy these days and you took advantage of that, was well thought, good job, I hope to see a bit more challenging games from you in the future, something that I could call "games". :)
