Thanks a lot! This is a really good feedback for us, especially for my cousin who made the game with me (he was responsible for the most of art and all the songs in the game and, by the way, was his first experience both participating on a Game Jam and making an autoral game).
About a fuller game following this idea, it could be interesting to make, but we'll see how things goes after the evaluation time's over. I already fixed some bugs and made minor improvements on the build, just waiting until I can update it!
