Bob's World

Description
Bob's World is a free-to-play Super Mario Bros. clone for Android. As Bob, run and jump through the levels to rescue the princess.
Evil mushrooms, snails and other creatures cross your path, but Bob can jump on their heads to defeat them.
Blocks with a heart symbol can be bumped with your head to reveal their contents; either coins or a power-up such as a potion (makes Bob bigger and stronger), a bomb to throw at enemies or a shield that makes you temporarily invincible. Coins are kept between levels and can be exchanged for power-ups. Spare power-ups can be kept in storage, to be used when needed.
There are ten worlds to complete, each divided into 16 levels. Some levels change up the pace by taking place under water, making Bob swim through them.
