Overall it was a neat concept. Either knight stops zombies blue Knight can stop ghosts and Orange Knight can stop skeletons. Though with a name like "Spinny Knight" I was expecting their collisions to do something special rather than just spin... I get that it makes their positions change and creates some confusion for the player overall but the game felt a little lacking. Music wasn't to my taste but it was relaxing and chill, though I don't really understand what it has to do with knights? I would have made the characters bouncers or something and changed the enemies to people trying to sneak in maybe?
Stronger together as the theme works here but could be improved upon overall. Maybe if when they spin they move faster it would encourage having them collide more often.
Overall well done!
