Love the polish! The music is absolutely fantastic, and the graphics are great. I was surprised at how big the map was!
48 hours is NOT a long time at all to make ANYTHING let alone a game, so great work on even finishing!
If you were to continue working on it here's what I would suggest...
-A straight linear game like this I think could be done, but it'd have to be surrounded by an incredible story.
-You could also go the route of making a more interactive experience for the player. Give me some decisions to make... maybe there's a fork in the road and I have to choose which way to go... Maybe during the battles, I have a second dice that I can roll to heal. I lost in the graveyard and didn't have a whole lot of incentive to replay because I didn't have any control over what happened.
-clicking the dice on the corner to roll is fine, but for a bit I was confused why my player was only moving a few squares when I thought I had rolled a 6. That's just what the roll icon always displays. I even got confused again later after I had already realized this.
-I had some kind of bug the first time I loaded up where the buttons didn't display so I couldn't start the game.
Overall, I think you have a great foundation for a game here and I could see it becoming super fun if you keep at it!
