@Elsa yes, but, it can be like dreamworld but all levels are hard, harder, nightmarishly hard, and then another level of hard, so a chart should look like this:
@Elsa i mean after a press of a button, in alternate harder version levels that are normal, become hard (aka it bumps up the difficulty of levels by 1 with the press of a button) (maybe we can reuse dreamworld!)
red: i mean level 10 (it is hard,) becomes harder level,43 (nightmaeishly hard) becomes a harder variant of nightmarishly hard and level 59, becomes a nigthmare level
