I have now added support for transactions via credit/debit card through stripe as required for itch.io!~ Please let me know if this issue is resolved on your end ^.^
I intend to add a few variations ^^; but probably just 3, things like lightning was discussed, but adding that via this plugin may not necessarily be feasible. as it's not necessarily possibly via the formula used to generate the effect in the first place, although... it IS possible to add a layer of lightning on top of this, so it's... still a posibility? Just depends how things go ^^;
But more effect types will definitely be added! :)
