Comment: I post this because I runned this game for like half a year without knowing that jumps can be buffered. Then my life changed when I discovered (and it was so simple o.ó).

Buffered Jump (BJ): To perform a buffered jump just hold the jump key while Hocus is in midair. The important think is to start the press while Hocus is in the air, then he will do a frame perfect jump right when he touches the ground. The only exception to this is when the camera moves up, so there are certain parts where is better not to do a BJ. The input has to be started while Hocus is in the air, if you jump and keep that key pressed until Hocus lands, a BJ would not be performed.

Buffered Arrow Keys (BA): You can buffer the Up arrow key while Hocus is walking by just holding Up arrow key. This is useful to insta-press switches. Just one switch will be press for every buffered input, so if you have 4 switches you can buffer the first and then you have to do extra inputs for the others. Another usage of this is buffer Up or Down before getting in an elevator.
