I promise that i wanted to add it but i never worked with sound in unity before as its one of the first games ive actually made, so i will make it have sound in a future update. I just couldnt make it work in 4 days..... Sorry...
No need to apologize, that's where the fun is in a jam ! You do your best, and you learn. The point is not to have everything good but to gain experience and to have fun. I was just discussing my exprience with your game a bit. You did great either way :D
