No, actually. :V
I actually thought of it on accident when I was trying to decide on how to do a timer for the attacks.
Not to say there could be a game out there with a similar thing- but I don't know any that have done it before.
Originally, the abilities were each going to have a cooldown, and you connected Runes in each of the Abilities' own tabs.
Then I thought to give each the same timer, and you just use any ability you want. But then players would focus hard on just one Ability, and I sort of wanted that Ability cycling Vampire Survivors had.
So I asked the questions:
- "How do I auto-make-sure an Ability is selected?" Because I don't want the player constantly selecting the ability. (Tedious)
- "How can it cycle through the Abilities so someone doesn't pick the same Ability?" Variety and "forced-to-use-what-is-given" philosophy.
- "How can the player change the order?" Control on timing and "combos".
Then, when I was testing placing the Runes and put one above the other on the Grid, I was like, "Huh... It's sort of like a calendar."
And that sparked the idea into what it is.
