Sincere apologies for the late reply, well, surely!

Honestly, I see no need to credit me at all, the code from this mod is practicly just taken and altered from the base game itself, so you arguably did nothing more than I did, just with an extra step.
If you realy desire to credit 'me', just note somewhere that this mod is the inspiration or so, but in all seriousness, no need for anything.
Hope you'll do well!
