Hi everyone, sorry I haven't responded sooner - I've been a little busy and sometimes responding to comments takes a really long time. Like, 'no time to work on the game today, I've got to respond to all these comments' long. So I will say I've been taking note of all the bug reports and either fixing them or putting them on my to do list. I'm also listening to what people say both positive and negative, and what people would like to see. The full version will have a lot more in store - not necessarily everything that everyone will ask for (it's not all practical) but I will try to make the system as compelling as possible. I think once the 'post sex scene' sections of the game are more fleshed out you'll see the shape of the game that I'm going for a little better, though; I think the demo and even the alpha versions don't quite capture that yet.
As for stuff about the game balance or difficulties with combat - yes, the demo is pretty hard.
I won't give hints because I like to let players discover and share strategies but I think some people in the thread already have a pretty good handle on things. The main game is easier because (and I'm not sure if people have noticed this, although I had thought it was clear) the maids gain skill points depending on what jobs you give them in the mornings. That means they will get more and more powerful as the days pass, and the full game has 21 days, and they also get access to a bunch more spells as well as some items. You can't advance love and lust as fast in the main game as you can in this version, but you won't need to.
Anyway, I appreciate all the feedback, it's very useful and I try to take it all into account. As the developer I'm a little too close to it to be able to know what it feels like to play it for the first time.
