Question Tower Defense Minigame

I had a 1.12 mini game server but I noticed a cool game called tower defense in minecraft. I looked for plugins and saw none for 1.12. I turned my server to 1.8 because 1.8 was the latest version available. I tried and it did not work. However I tried 1.7 and it worked. Is there any way I could find a tower defense plugin for 1.8 or higher? Thank you.

Here is the plugins I tried

For MayhemTowerDefence, he was last on four days ago. For MTD, that guy was on back in April. Try PM them and ask them to update or to give you or someone else to update their plugin. Make sure you include that last bit, because if they don't update, you will need that permission in order to ask someone else to port their plugins to the newest update.

 

Thank you
