New Touch Controls

I've experimented with different touch controls for the game.

First I implemented on-screen buttons and a responsive UI that moves the map to the side (or up in portrait), making room for the buttons.

However, I felt that might not use the device's capacity.

The latest version contains a different experimental control scheme:

• Tap a field nect to Panda's current position (and infront of him) to fly there.
• Drag a path from Panda's field to where he should fly (multiple fields).
• Tap Panda's current field to turn around.

I do like it, but it feels a bit fiddly on my iPhone 12 mini.

Let me know what you think!
