Royal Defense: Invisible Threat 2.8 5 29 29
Thumbs Down Didn't play the whole trial. It is not clear what you are supposed to be doing, the tutorial doesn't help much at all. Just didn't float my boat. Uninstalled. June 12, 2013
DON'T BUY THE MAC VERSION!! The Mac version of this game is nothing like the original. In the original games (and the PC version of this one), you can replay old levels to get more gems and upgrade your weapons, spells, etc. There were also three difficulty levels: easy, normal, and difficult. The Mac version of this game has only one difficulty level, and you do not receive gems during gameplay. Instead, you get a predetermined amount of gems based on how many shields you get: 5, 10, or 20. And if you replay a level, you can only get more gems if you improve your score. I foolishly bought this game and can't get past level 11. Waste of money and time until they update this game June 16, 2013
excuse me? I like tower games and played a lot of them - no need for a tutorial really, youll get the hang of it real quick. Usually... this here though is ridiculous. You may find out how to get rid of the invisible threats eventually, but the game stops for you right there at level 4. What the hey? Before that you had loads of money to spend and a handful of threats. All of a sudden you only have 55 coins and massive incoming threats that will kill you on the second wave. I have tried 5 times and gave up - that kind of challenge leap is hideous and kills the fun right at the beginning. very unfortunate June 12, 2013
Not good, but could have been This game has the potential to be good. The major problem is that there are no clear directions. You have no idea how to kill the invisible creatures so you literally can't get past level 3! The gun upgrades are not clearly marked, so you have no idea what kind of upgrade you are choosing. What is supposed to happen when you click on a creature and the little target shows up? What are those little spyglasses on some of the building areas for? I read the other negative reviews and was excited to take on the challenge, as I consider myself a pretty avid TD player. But nope, this game is ridiculous and completely unplayable as is. Please - game developer person - get a better English translator and write some REAL directions and a REAL tutorial and clearly mark what things are. If this happened I think the game could be pretty good and would probably buy it. June 11, 2013
nothing to help you with this game is stupid there's no instruction doesn't let you stop if you're having trouble nothing I wouldn't buy it if you pay me to why waste my money on something that you don't understand or you can't enyoy June 12, 2013
What the Heck???? This has to be the silliest game I've tried in a long time. No instructions on how to play it, and nothing I tried worked. There's not even an exit button to get out of it! A huge "thumbs down" from me - it's a complete waste of time. June 11, 2013
Terrible Worst game I've ever played. No fun, horrible graphics and sound. Don't bother. September 5, 2013
I quit on level 1 That really says it all for me. No fun, no comprehension. Uninstalled with lots of time left on trial. June 23, 2013
Ugh "forced" tutorials Not a fan of forced steps in tutorials, I kept the tutorial on, since the first part told about the new stealth units, I didn't want to risk missing something else. So after each completed level I had to either upgrade the guns, or restart the game (after EVERY level). Those who completed the first game will know gems shouldn't be wasted like that. I'm also not sure why they offer a windowed mode, when the window still takes up the majority of the screen. The last is a dealbreaker for me. The game doesn't realle need "complete and full attention", so this would be the kind of game I play while wathing movies or youtube. The trial wasn't enough to know if they ironed out the bugs form the first game that was never fixed (game freezes, occationally returning to default settings on its own etc). June 12, 2013
