Keys and Locks

This is a 4 level platformer utilising keys and locks. Move with arrow keys and jump with space. Use UP and DOWN to interact with ladders. R will reset the entire game, and L will reset the level. Level 4 is quite difficult, so here are some tips: Your jump height depends on how long you hold the spacebar. Also, you can give yourself some leeway by grabbing the key display in the upper left.
