not too bad, just started playing with 1.4a. Combat is ridiculously easy once you grasp how red demon and yellow demons forecast what they're doing.
If you're good with the combat and thus can come back with 5+ food every single day, the Emma (former mother) gets corrupted VERY fast. By contrast Kelly (former sister), takes a ridiculously long time to 'grind' her corruption up since her vibrator battery needs aren't reliable (sometimes she needs 3 days, sometimes she takes 5 or 6 to ask again)
Issues I had, despite finding combat 'easy', the beginning health/mana pool are VERY low and leave little room for mistakes. Resorted to massively save-scumming, and even that isn't reliable if you bump into the yellow biter demons too early (shield and dark fireball too low a level to be useful).
Inventory room is also insanely low, really need to find slowly increasing bags as you continue playing. Small backpack (+4 inventory), large backpack (+8 inventory), small duffel bag (+13 inventory), Large Duffel (+20 inventory) for some examples; 7 is simply too low after ~14 days ingame.
Alternatively, things like "random chocolate bar", the batteries and possibly potions no longer count as 'inventory' because they are easily pocketed, small items. Bottles of wine, "fresh fruits and vegetable" foods, and the demon hearts being 'larger' items, should continue taking up inventory.
Aside from the inventory & stat issues.... not bad, not bad at all. A game to watch, but once you hit the end of the current content, this game has little to zero replayability. So bookmarking with the current date, and I'll check back in 3 or 4 months to get several patches worth at once.
