I really hate this game. I can't even make it past the tutorial, because there is only one life. I get cornered on the boss level every single time, and just as I'm about to win, I get touched by a zombie. I have played the tutorial levels 10 times, and cannot get past them to actually play the game. I thought the point of a tutorial was to teach you the mechanics of a game, not frustrate me and leave me wanting to give up trying to play this game.
I just played a super long level and managed to finish it by the skin of my teeth, except that once the final boss was dead, the game refused to acknowledge that it was finished. I could still upgrade towers, but no finish screen. I don't think the badges are worth it if I have to play the levels multiple times to get it to register.
The stupid elevators keep refusing to switch floors. I make it all the way to day 15, then die because I can't get to a floor that has lost an elavator
