Knightfall
You are a knight, some weird thing appears before you and kidnaps the princess, at least I think she's the princess, anyway she gets kidnapped and you have to get her back. You have to get the key and open the door(the grave looking thing) then get to the door to get though a level. To get the key you need to rotate the screen using the arrows next to the screen and destroy blocks by having three on the same kind touch and double clicking on them. Beware of enemies, they will hurt and eventually kill you, drop on top of them to kill them. And don't forget to collect the power ups, they come in handy.
