[n8hopp]

Add some basic puzzle implementation in the base project; below is a list of possible elements:

• [x] Locked Door
• [x] Unlock Signal Key (Unlocks door with signal upon pickup)
• [x] Small Key (need to bring to door, uses key resource upon unlock)
  • [x] might be reliant on inventory system
• [x] Pressure plate
• [x] Movable/Pushable Cube
• [x] Switch

as of 4729a20 i've made all of the puzzle blocks in the list itself; still thinking of some possible test implementations of a couple of them
