End game play could use some work. At a point it becomes way more profitable to just be doing investments than anything else... just wait until good kingdom news and rake in the returns.
Overall a solid strategy rts game. A few things I noted: the initial zombie hero was all I used throughout the game, the last 5star skill is great for taking out waves of enemies especially if you get them lined up across the lanes. That being said I wish there were some other upgrades I could use my stars on (maybe increased gold mining, small base upgrade to other characters etc.)
A good strategy that I found worked for most was to start with 2 miners each on the 2 lanes with the closest gold mine, as soon as one miner drops off gold you should have enough to upgrade the gold mining. I will typically designate one lane my "gold lane" where I will do everything to protect that a group of miners vs trying to protect all 3. From there send out small waves to keep the enemies at bay, but not enough to really damage the enemy castle (if you do too much damage early the difficulty ramp will smash you). Keep upgrading gold when you can and then build up enough gold/magic for an assault.
Pretty good strategy for all levels. Start with area burst and put a range modifier next to it. Advance send 7-10 waves and upgrade area burst start to add basic and upgrade it to kill ghost. Advanced send 5-10 more wave and start building fire rate tower and upgrading, build these in a 2by2 so you can then upgrade to mega tower. Once you have all 4 towers and a few upgrades you can advance send the rest of the level.
such potential.... just add some more depth... maybe getting to chose the development path of your dragon... not capping it at 600.. and adding some more unique items that bosses drop
The pairs of blue symbols have no significance... yet :D
