I was really excited at first engaging characters. It seemed like a fun game. But, the algorithm is set to be very hard not to far into the game. I spend a lot of money on games. But, I won't pay just to pass a level early on. The game is set up so hard in the early levels it takes a lot of time just to get past. With very small rewards. I usually spend my money on games that are fun. It's not fun anymore if they have made the levels to hard on purpose.
