It's now possible play the entire game with just the keyboard:
WASD - Move obstacles and/or kill enemies by firing the wisp energy;
Cursor Keys - Move player;
E - Activate lever;
R - Restart from checkpoint;
Fixed issue that occurred after loading a checkpoint (player position not set correctly);
Fixed the position of the obstacles when near a jump platform;
Fixed issue caused by the new fast movement option (timing between obstacles and enemies were wrong);
