Player blob is in, with controls and basic collision detection. Enemy ‘attack’ logic is in, and they can be made to destroy each other (although they just disappear for now)

Unfortunately, the game is probably going to be much simpler than originally intended, with just one enemy type. I’m going to concentrate on making it a bit more playable (game progression, player death, etc), then decide whether there’s time to add another enemy type, or to add death/destruction effects for the enemy/player/rocks
