!!Environment objects

!Switch Ball
These circular shaped switches, when activated, trigger a timer which a nearby obstacle will be activated for. They can be triggered by a number of things: any form of hammer swing, harry himself, enemies, hammer blocks (generated by hitting an enemy with the wooden hammer), and rockets triggered from their respective blocks. Once activated you can not turn them off again until their designated timer runs out or you reset the room via start menu.

!!Special Blocks
!Hammer Blocks
These blocks are generated by hitting various enemies with the wooden hammer. Once spawned they can be hammered in a left or right direction as long as there is open space (with the wooden and pico hammer only). If you have the metal hammer out instead, the block will be destroyed with a hammer pound.
