The game itself is great, awesome & much more! But I found some-I think-bugs in it.
1. Some upgrades seem to be disappearing, for example I have bought the loot II upgrade twice already, and now it still looks like the other ones that haven't been bought;
2. Sometimes I was finishing a level with 2 stars and the game gave me only 1 upgrade star;
3. One time something weird happened to me during a game, when the bought shrunken tower... just vanished!
Anyway I'm not giving up and aiming for finishing the game!
