We sadly had to put in the first drafts of the music since we had some time issues. The updated version of the game has some better looped music and a special soundtrack for the third stage.
Omg!! 15 Souls by stage 3! You're insane! Even we didn't manage to get that much and even I need 2 tries to even get to the outro xD We are working on the difficulty and the stage length.
Thank you so much for your feedback :)
