This is such a creative and fun game! The fact that points are just there for enjoyment is really nice, and this game does a super good job feeling comfy and cozy!! I had a lot of fun just typing the longest words I could think of, and trying to close the loop at the end. It all feels really well polished, and like a lot of though and care went into it. The witch character is really fun and nice as well!
For a little bit of feedback, I would be that it's a little bit unclear how the circle is supposed to close, because it looks like you need to type the first three letters of the starting word to close the circle, but just having the first letter of the first word at the end of the last word would close it as well. Maybe something that could be cool would be allowing the circle to be closed by only using 1 letter of the first word, but giving extra points the more letters you use? I also think that it'd be cool if once the circle was completed, the common letters of the two words were combined, so that it makes one big continuous circle (ex on your screenshot of a completed circle it shows plateearth, but having the last e removed on plate to make platearth)
Anyhow, these little things did not reduce my enjoyment, I just thought I'd give some ideas, overall, really great game all around, good work!!
