Nice little game. I liked that you added a tutorial, even though it was very easy. It helped to get into the gameplay loop. To be honest I did not really get why you need to roll the dice. I think it would have also worked without rolling a dice. Just open the chest and you randomly get what you want. I missed the functionality that you can remove items from your inventory when you opened a chest and got something nice in it, which did not fit.
Congratulations to this game!
