Really nice concept, one of the better "rolling a die with the face up side determining your action" games I've played! I generally didn't like a lot of those that used regular numbered die as I find it very hard to know what number I'll get when rolling, but here since you can customize the dice that's much less of an issue!
Some potential areas of improvement if you want to keep this as a roguelike: the goblin AI is predictable and the fact that you can try to move into a wall in order to stay in the same spot while they come toward you makes it a little easy to exploit. The First Aid ability is also very overpowered, once you get that pretty much the only way you can die is to play extremely badly and/or get trapped on 3 sides by goblins. Also once you get your die set up the way you like there's no point to collecting more powerups.
I say "if you want to keep this as a roguelike" because I think this would actually be a great framework for a really simple but engaging puzzle game! Much more than all the other "roll the die onto the correct face" puzzle games in this jam. Have specifically made levels where you give the player a premade dice layout, health amount, etc, and they have to find the right sequence to survive and escape!
Nice work!
