It's interesting, engaging enough for it's short playtime, so I'd say a successful jam game. Nice chiptune and goopy monster sprites as well.
As for feedbacks, probably should've said you have to drag the dice, i was clicking all over trying to figure how to operate it lmao. Also it feels weird that the dice don't stack values if you double up on something. It's pretty much impossible to beat the boss if you take the heals instead of the dice which feels odd. Also I feel like you should be able to move the dice after you place them, doesn't really make sense for them to get locked in.
Anyway, fun little thing. Good job.
