We have actually mentioned it in the description. There are a couple of dev notes that we have provided. We suggest you to read them first before playing the game. It has been mentioned there that the Enter button has to be pressed to proceed to the next screen :P
As it was our first game jam, we didn't realise how the time crunch would be and art isn't really our strong suit :P so we tried our best and we didn't really have any musician on the team so that led to the lack of music in the game.
Anyway, thank you so much for playing our game! Glad you liked it :)
