It's disappointing to come across a classic game that's structured with the pay to play system. Yes, technically it is "free to play", but this comes with so many strings attached, I'm surprised I didn't accidentally strangle myself in the tutorial. If an app is going to charge you, just make it a purchased app, rather than "pay (or wait an exhorbatanat amount of time) for more credits to play!". Unfortunately, unless this changes, I won't be re-installing anytime soon. Do better, Mattel.
