Very boring and time consuming gameplay these loading screens at each stage within the levels are very annoying

I found that if you don't spend money in the later stage of this game, the game experience will be terrible!

Excellent game but this game is not free to play. If you want to play more and if you want to win you must purchase. It's not a free game. Stages are awesome but the increase in stage will increase difficulty too and you will have less materials, poor heroes and many problems.
