I could probably spend hours coming up with potential Dead Cells updates. (Like, minor changes and stuff).
I already have some ideas, like making the Death Orb and Gilded Yumi Tactics + Survival, adding an option in the menu that changes the DPS out for the damage per hit, an option showing how much health a boss / enemy has (As a number), an option that shows you how many enemies you've killed overall, in the current biome, your highest kill streak, how many enemies are in the biome, and how many are still alive.
