So the defense and the monsters are really nicely designed however the towers need a little more upgrading for example for the first tower when you upgrade it to the last level it should have some effect upgrades like idk splash slow or instant death some nice effect would make this a very very nice defense plus u guys need stronger monster its really easy and for people complaining that sometimes u don't even have enough money to build a tower it's a strategy game morons that's something u need to figure out how to get money . Anyway I loved it worth the money keep it up guys

Although I've had fun playing this game I don't feel it's worth the $3 I payed for it because many of the levels are glitchy, sometimes I will start a level with about 100 gold and then ill restart that same level and have 0 gold to start and randomly receive the 100 gold I should've had at the start after I lose half of my castle life. Very frustrating.

Royal Defense is along the lines of Kingdom Rush except on this game I have to think and do math. Haha The nerve!! Hurry up with more content!!

The new graphics work, however the new 10 levels will not open. I get error message when I try to click on it.

Levels that I was able to beat are now impossible. The game spams 100's of self healing units. Please fix!

The uh.....new maps/levels you just came out with, I can't open or purchase it.... So how can I play? Overall great game though.
