Hello thank you much for taking the time to write such a review! 1st of all, the evil menu os not the easter egg, it is what you get after you get to level 3 so you don't have to replay from level 1 if you don't want to. To give you a clue: the easter egg is at the evil menu! All your comments are absolutely on point! I'm planning to add rythm in the future when I get the time (I just did another Jam sooo...) and I chose this song especially because it works good like that! To be honest, I changed the song just before submitting and I play the game exactly as you do, with timing in head! :p
Again, many thanks!
