Addicting but I think there's an xp glitch that needs to be addressed
I'd give it 4.5 stars if I could. I was going good beating all the 3 stars on veteran and then I got around 20-30 and I started getting ridiculous amounts of xp. I would get in the 100k's per game and then for the ad thing as well. Then it started to go up and up and up as I beat more levels to the point where I was getting in the 100 millions of xp per game and for the ad thing, which I stopped doing. I had more money than I knew what to do with and upgraded the first 3 towers to 150 damage, 150 range and I place one of each of those fully upgraded towers at the beginning and wait for the game to end. I had upwards of 10 billion xp if I had to guess and I just checked and I have -1.5 billion xp, like an actual negative number. It says I need to get more xp for upgrades. I am getting xp though, like the negative number isn't getting more negative it is moving towards 0. It isn't a problem because at this rate I should be back to 0 in about 10-15 levels in my estimation, but it kind of hinders the playability if I can just get the tower attributes to ridiculously high numbers insanely quick. Again, I absolutely love the game itself, however this unlimited xp glitch is making the game uninteresting to play because I start a game and use 3 towers the whole game and just sit back and wait for the level to end so I can start the next level and do the same thing.
