Keep Him Alive

Hi Everybody, This is my entry to Ludum Dare 46 ' Keep It Alive' jam. You play with arrow keys. Your goal is collect the key, open the door and move to next level. But...The tile you're standing on disappears after random amount of time and you fall. You also have to avoid the enemies. There are four levels ( made just in a weekend ) but I think they implement the main idea. I will continue the development... Thanks...Have fun...!
