No worries, 48 hours is incredibly tight for making what is essentially software, my game sucks :D
As a role model for this type of game I'd recommend you check out DIE-SECTOR, it tells you what number you'll roll on, which reduces the hit-or-miss feeling. Its not my game and I'm not being endorsed to say it btw lol, I just think its great and follows the same concept you're doing. Good luck!
