Ive been playing this game since the first release. I find it very challenging and it kept me entertained through long flights, barber shop, etc. There is nothing to dislike and I decided to post this review because those giving 1 star ratings to a very well done and enjoyable game are just making things up to complain. If this true old fashioned tower defense doesnt entertain you, the problem isnt with the game - levels are challenging but not impossible, the game never crashes, and there is balance overall in gameplay. Every turret is different, you have to learn how to use them properly. To the author, Artem: Please make a 3rd episode!
