Escape From the Pitchy Forest

Basically, you need to drag the left half of the screen to move, and drag the right half to move the view. If you pick up an item that is falling along the way, you can touch the item field to use it at a specific place. There is one monster roaming the stage, and if you are attacked 3 times, your game will be over, so explore while avoiding them. Eventually, the game is cleared by defeating the items that pick up the monster.
