Royal Defense: Invisible Threat App Reviews

To progress on a three star basis you need to buy extra power via In Game Purchases. This is not how this should be. There is no encyclopedia of friends and foes so you only have the notes provided when a monster appears for the first time. No information on monsters when you tap on them in the action. No there is also no reset button to undo your power ups or your character so you can start again and use a different strategy or ratio of power ups .

Ne marche pas !!!!

Could be a 5 star game with more levels. I completed the first campaign but theres no way (and no instructions) to access the 2nd?

Why is snowfall mountains locked? I finished forgotten fields with all 3 stars but, snowfall is still lock, it this a bug ??? How do I get to play/unlock snowfall mountains ??????

Why is snowfall mountain locked even after I finished the first campaign. Good game but glitchy.

Wont load at all, No Go...No stars! sorry.

They removed the ability to replay levels to get crystals, which now kills the games replayability and fun.

Game has so much potential but plagued with bad patch releases. Not worth .99 at all. No way to continue upgrading the towers once your done so when its over its over. New patch death bone cant even play it, says you have to purchase it but you cant. Im done having hope in this game. Take example on kingdon rush and release a finished game pls.

Easy game to learn. Addictive.

First two campaigns are fun. Then the third one requires you to buy gems... Ex.level 3-1 has 5 out of 14 emplacements locked...PC version has 1.

Ottimo Tower Defense.

Fun TD but wish more levels/campaigns were available. Looking forward to future updates. I have an iPhone 5 bit didnt experience any problems that were cited in other reviews.

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 dont even have enough money to build a tower its a strategy game morons thats something u need to figure out how to get money . Anyway I loved it worth the money keep it up guys

Fun and challenging

Although Ive had fun playing this game I dont feel its 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 shouldve 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 100s of self healing units. Please fix!

The uh.....new maps/levels you just came out with, I cant open or purchase it.... So how can I play? Overall great game though.

Cool game but the final level will not unlock! Help please!!
