Finally gave 0.4.9 a shot and holy shit is Harem mode bad. It's clunky at best with how the UI works, we have to click on the two actors, click on the action cards, then wander through the facility to find the appropriate furniture? Why are the doors even closed, they serve no purpose other than to add more keys to press. From a user experience design the fewer clicks you need to perform an action, the better, and Harem mode fails horribly in this regard.
it should've been multiple rooms, each with its own monster/girl, and the character you're playing just needs to interact with them to open up a list of available actions, and it'll automatically place you on the nearest valid/available piece of furniture to start the action; if you want to change location or action, you should be able to do it from within the current action (which they clearly have the code for, they can do it in Classic mode, so WTF?).
I can't even begin to imagine what a clusterfuck of horrible UI decisions the base game will be like if Harem mode is any indicator.
