I have added the tag mana-engine. This tag is here just in case you wanted to write your own game content for MANA.
Simply, add this tag to any content you write and publish here on itch so it can easily be found.
I say it in the read me but I'll say it here too. MANA will always be free, but if you write anything for it, you can charge whatever you want as long as you direct traffic here for the original rules (that means please don't include MANA core rules in your own documents). And also if you need assistance in writing, layout, or maybe graphic design feel free to ask me.
