The game was made in a good effort, but it's all about grinding and there's no real point to it.
The music and FX ripped my ears apart after the first two hours.
Because of the extremely high prices and slow speed ( Yeah, it's still pretty slow even after the update) , it's taken me about 8 hours to get all the medals except the 2nd secret medal.
The game is fun for about 15 minutes and then it becomes monotonous, so you get 4 stars.
The only thing that made me hang on for those 8 hours was the set of MEDALS !!!
So, the next time you make a game, be sure add lots of medals... Cheers :D
Oh, and can someone PM me the 2nd secret medal, it's the only thing keeping me from my 100 points "All the medals" medal
