ideas
it idea is good, you are on to something that can be really good.
One thing that I notice while playing is theres no end. Once you get a good house production up with 4 warriors you can pretty much sit back and let things take its course. The reason I say 4 warriors is you have the code set up to only send a max of 2 "monsters" at a time. Which brings me to my next point, a simple fix would to have triggers where once you hit day 'X' then the number can increase to 3 or 4 or every X amount of days the number of monsters will increase by 2.
The help menu you have is very good for a small game like this.
Sound - For the love of God add a mute button!
The idea when making a game is to find something that keeps you interested for 5 minutes, then expand. I played for a good 30 minutes so you have something just expand it now, ask some of the more experienced developers on ideas and codes to use.
Hope to see an updated version soon
