Having akimbo revolvers that reload independently was neat as it allowed me to save a good roll in one hand while I fended off enemies with the other. I liked the way they controlled too - the aim offset was pretty tricky but I actually felt it to be a fun challenge.
The narrow ramp of the towers was a bit tricky to climb with the high move speed, not that I ever really needed to go up there. I feel like maybe there should of been more of an incentive to use the correct die on the correct enemy too - I liked having to line up specific shots but it seemed easier to just spam dice at them until they died.
