Here's some more info you might wanna know.
They added new stat system much like Fallout (STR/INT/AGI/END/LUST/CHARM). They also added a 'Telltale' character system (they will remember that) and a interaction system (Touch, Kiss, Grab). The 0.1 Beta will be open to public on Saturday. It is the first half of the two part prologue. the setting is when MC is initially sent to hell and makes the deal with the Demon Queen and will also only be containing straight/non-futa content. The second half will continue the prologue in the hospital, much like in the original version. Also they took out the spider demon lady, so if you were into her, sorry.
