To be totally honest, the music is pure improvisation. My teammate played a couple of minutes with different rhythms and styles, then we cut into the track to keep the best parts.
So, the game seems simple for you but have you reached level 20 ? Level 20 is when the game starts to be really difficult.
And yes, I added this win condition (serpent stuck) because I knew it would make people try and try and try to achieve it. There's even 10 bonus points when it works (but sometimes it is quicker to simply use the door).
Thanks for playing !!!
