Looks very pretty! Nice to see an RTS game featured, I used to play a couple of them as a kid, though never very well.
I played for 7 days, then got bored and quit. Is it intended that almost all blue troops spawn on the right? Also, that they don’t care for my buildings and just attack my troops? I don’t really feel like I ever was in much danger or had much to do.
I think this game doesn’t need much to be fun; mainly something to do while waiting for troops. Maybe have a hospital where units can go to get healed. Maybe damage buildings that can be repaired. Maybe some other form of resource gathering.
Visually, this game is great and I also quite enjoy the marching soundtrack. I think you could turn this into something pretty cool with a little more work.
