Our game was far too simplex when the enemies just spawned in the room all in the same place and in the same order and this wasn’t liked as it made the game boring very fast, so we decided we would change this very quickly, as its a thing that makes the game unique so we know our game is its own game, we have implemented this function to many parts of the game now, as a lot of our power ups randomly spawn now just like the enemies, also we have implemented bosses to the game that also have this function, in image form these are the things that are involved.
