Apparently, a penguin was found today on a New Zealand beach. Obviously far from Antarctica. Just a few short days after this game's release. Coincidence? I think not!
True, Ilfirin, it was just one of the things that came to my mind. Don't get me wrong, I love most of the ideas in this game, and the unique additions are EXTREMELY refreshing, but some of them are just broken. Although I would have to agree, making a kind of tower able to hit/decloak them would work just as well, although I would say it should be any of the Crypt towers, since they feel underpowered except for the ability to fear on a random chance.
By the way, a few suggestions on things you could do to fix the cheapness of the Ninja/Thief enemy class would be A) Remove the Ninja/Thief enemy completely, B) Shorten their invisibility from 5 to 2 or 3 seconds, C) Make them visible the SECOND they grab a gem (and possibly take double damage after their invisibility wears off, visibility alone would still make them OP,) D) Give them significantly less health to improve the likelihood of instant-killing them before they can even activate invisibility.
This is a great game, but for the love of GOD, FIX/REMOVE THE NINJAS/THIEFS. They RUIN this game! Once they show up it's impossible for me to get a perfect ranking no matter how the hell I place towers, and past the 3rd level I never got anything above a "good" ranking. This would be my absolute favorite TD game if it weren't for those enemies. There's no way to combat them, even if you hit them the second they enter the room they almost always make it to your gems, and usually get them far enough so other classes can finish the job. I absolutely cannot overlook a flaw like that while rating this game, so I'm going to have to give it a 2.5/5, where it would be a 5/5 if you hadn't overlooked that glaring issue. How they got past your beta testers I'll never know..
1143 seconds to everything unlocked+all badges :D This game is pure awesomeness, I always felt upgrades didn't get enough credit in the video game world. 5/5!
