At first I was surprised by the dice mechanic, but after a couple throws it felt pretty natural and the concept turned out to be really fun.
One thing that stuck out to me right now is how overpowered the plunger seems, but I think it doesn't need a nerf so long as the levels are designed with it in mind and the ammount is always kept low. Enemies could also have ranged capabilities later on so that using a free pass on close range enemies doesn't invalidate any difficulty the level might have.
