The concept is fun, but for me it is not really connected to the language theme, however, I think that it would fit perfectly for a book theme. The puzzle are funs, but the Red cube stucks too often against the walls, so it is kind of frustrating. I think that if you fix this issue, and add some feedack sounds + music, it will improve a lot the game ! Overall, gg to you for your work !

Really cool idea! There is a sweet puzzle game here.

this was fun! Love the concept of it :)
