I think this is a very solid base for a good future game, attractive dynamic gameplay!
The idea of "turning over" a map is not new for this jam. There are many such games where player rolls the map to solve some kind of a puzzle. But THIS game brings dynamics in gameplay. The same idea of "rolling the world" but instead of it you focus on surviving, that's great.
It would be great if you can add some lore after the jam to it. Throw "dice" themselves in the garbage and make it a "magic cube" instead. For example, some wizards invented this cube but after some failed experiment the cube came to life, threw its creator to its top, and began to call different creatures, so the player (wizard) should fight them back and stop this cube from rolling... Something like that))
I understand that you didn't have enough time to do a proper visual for the characters and enemies. But for me, it comes as a second priority. First of all the gameplay, and it was good!
Hope you will continue the development and will make a good solid game from this base :)
