I liked this game!
Some of levels felt a bit longer than they should've, especially some of the earlier ones, but I think, that overall, the level design in this game is great!
I also liked the art and the little narrative you did there! And the music, even tho it wasn't made by your team (I assumed so, because you said you used pre-existing audio in this page), manages to capture both of the characters that you control, in some way! Good job!
