The jam's theme is border and direction and it can be interpreted in any way. In our case it's a gimmick.
Maybe it wasn't clear how the mechanic works, so it's confusing how it fits the theme. I'll add a proper explanation of the Delay Attack mechanic in the post-jam version to make it clear
That gimmick with delays is played out of enemies slot and core game play in your opinion isn't main mechanic? :D
