Here are some researches I'm doing about the enemies of CoinOpStory.
I was really wondering what type of enemies it can be. I tried different paths, like for example representing them as 'glitches'. But I had a coherence issue. (and it was hard to figure out a visual for different glitches...)
I finaly came up with the idea the enemies can be like Gen, the Hero : generic cabinets!
And like the big bad guy of the game, they use Bootleg games that turn them agressive.
[still Working on that idea)
