Thank you for playing! In fact, you can control the weights of the dice, for each beaten wave of enemies you'll get a new dice with different combinations of elements and then you can switch between them with Q and E. And if you don't like your current element applied, you can just "punch the air" to get rid of it (should've probably clarified that somewhere...)
I think charging the player a heart is too brutal for an already relatively hard game 😅
Thanks for the feedback!
