I really like this app... very fun, excellent graphics and gameplay. Controls are a little sensitive on my phone, but you can get used to it ...it makes it more challenging and requires a greater skill level. I'd give it 10 Stars if they had it. Wait - I just did! I played a lot of apps like this, and this one is on a different plane altogether. Cudos to the designer or design team. A lot of thought, research, planning, and work went into putting this baby together. Highly recommended.
