Lovely game, like Baba is you :)
The sound is good, gameplay also.
My one complain would be you end up having a hurt hand after a few level by walking all the way from a place to another, again and again, to search letters and form words. But I don't know how to fix that...
Oh and I am glad not all words were working, I would have ended up with weird red and purple butts (might have been funny though).
Good job!
