Missing things in the Engine

Things that are missing either in the DANG engine or the PnK code:

• Hero can jump onto empty bubbles and use them to jump even higher. Bubbles with an enemy catched will not work.
• Include joystick to control the king (should be the same as up/right/left pad).
• When Hero enters a specific zone (like leaving the screen or hitting a specific element) it should be possible to transport the Hero to another location within the same level. Like leaving on the right and entering on another position. Or hyper jumping into some secret location. What about special hotrects, always two have the same type and name (going back and forward).
• To be player friendly, we probably will need save points. Where we write down the current location onto the SD card and read it back when starting a new game (do you want to start from the beginning, or from save point XY?).
