The idea is to extend the already existing path activity. Here, the user does not have to walk on a pre-defined path and is free to roam around. Additionally, we have an `energy` property associated with `Tux`. The user has to spend 1 `energy` to move one step in any direction. Initially, `Tux` has a fixed `energy` value. This `energy` may or may not be sufficient to reach the destination. `Tux` has to collect food items along the way (say fishes), to replenish its energy to reach the destination.
Additionally, we can explore other types of `obstacles` used in the activity to make it more exciting. One such idea is that we have a river in the middle of the map, and the user has to cross the river using a bridge.
Adding animations to the activity would be a plus. For example, add scale animation to `energy` components on the map. This would allow the users to locate `energy` items quickly. Also, hitting a solid block from where `Tux` cannot pass should trigger some kind of audio/visual feedback. The possibility of adding animations to other components could be explored.
