Show HN: ChangeWord, transformative word game in 6 languages (changeword.org)

I just launched changeword, a daily word game where you have to transform one word into another by replacing or inserting one letter at a time. Each inbetween word has to be a valid word as well.

Changeword is my first multilingual word game - you can play it in English, Spanish, French, German, Dutch and Swedish.

Any feedback is appreciated! :)
