After watching Mysticat's video of Blockle (Wordle in Minecraft), I decided to make Craftle, which just like Blockle, is just Wordle in Minecraft. Craftle uses only items in Minecraft and should only use the items in the server version you're using. It has customizable messages, effects, and commands when a player wins. This took me about 2 days to make, and I could've removed some extra code, but I'm too lazy.

Servers running this:
ResistanceCraft (1.12.2)
play.resistancecraft.net (Mods required)
