Harmless Skeleton - a hardcore 2D platformer with survival elements in which you have to go through various levels for an evil skeleton named Skeleton. In this platformer, your main task is to collect keys that will ultimately help open the door to the skeleton house for you. At each level there are 4 keys, collecting which will open the very door to the house of Skeleton, after which you will be taken to the next level. Be careful, there are various traps and obstacles in your way. The skeleton is a very fragile creature, any incorrect movement, or collision with any obstacle will entail the death of this creature. But do not be upset if you suddenly die, because Skeleton only has one life to spend it wisely. If you die, you have to start the level all over again.
