Considering this is your first jam, and you made it in a much shorter time frame than what was given, this is alright. I like the idea of a 'survival' game with random effects depending on the number rolled. It's pretty neat and could be expanded upon in lots of creative ways eg.e the ghost(?) could be one of the dice numbers, obstacles in the play area could change position/shape etc.

Gameplay wise,  the controls were fine though the hit-boxes were far too unforgiving. I also couldn't move around the edges of the play area because of the obstacles. Not sure if that was intentional or not. Also, the only aspect of this that seems to be 'dice-roll' related is the fact that a dice randomly swaps between numbers. Why not actually make the player roll the dice? Maybe it could be an obstacle that you have to physically move around the play area.

All things considered, solid effort mate!
