BlobVaders ToDo
---------------
- Damage Actions:
	- Fall (vader falls down the screen, spinning as it goes).
- Kill Actions:
	- Gravestone (drops a wall on the screen which will take 4? hits to destroy).

- Current system could generate later waves full of low-difficulty Vaders.
- Redo vader health system somehow?

To Make it Better:
- Different enemy types (each blob pattern represents 1 type, types randomised
  for each game).
- Multiple levels.
- Bosses.
- Each level should have a specific goal or a theme.
- Player should be able to upgrade their ship by adding blobs (upgrade ship's
  capabilities as well as shape).
- Randomised pickups, Binding of Isaac-style.
- 'Overworld' map?
- Screen shake slider.

- Vader does not take actual screen size into account.
