Dead cells has something called assist mode. Doesn’t disable achievements or anything. Personally I use it as a second chance, the only setting I’ve touched is lives. Normally in the game you die, get sent back the start. With assist mode you can respawn (either at the level start or door you crossed). I usually have it on one life extra to avoid the “that was so bullshit” deaths but still keep death an actual consequence

It also has some stuff like bigger parry windows, lower enemy health and damage.

IMO it’s great because people can make the game as causal and forgiving as you want
