Retropaint hero app for iPhone and iPad

In 2002, my 6 years old son drew some characters and creatures using the mouse, from his imagination, based on films and anime series of that time.
I have reused those drawings, I have encouraged them and I have made an adventure game with them.
The graphics are original and hand painted with the paint, using the mouse. Other backgrounds painted with pencil and marker in the same year.
The operation is simple, there are several levels to overcome. Drive our hero and pick up his magic stick to eliminate the evil creatures trying to stop him from passing. Some objects can be collected to increase your power.
At the end of each level you will find a boss difficult to eliminate. Be quick and smart to end it.
Note: It is not a childrens adventure and has some difficulty.
