Pure runs are 100% possible, some side routes you will need to shut down like with Leandros as their route is aimed to corrupt the MC but other routes will have pure versions and the main story content certainly will. At the moment there is much more corruption content then pure as a lot of the pure will be scenes between Cam and Elora of a romantic and sexual nature and I wanted to spread out the content for other characters to start with. In the future there will be a date system for the two with many interactions, as well as unique pure quests and interactions, and of course endings and main story content. For example, you can continue with all of Jen's content to come to a pure, non corrupt conclusion by not engaging in the sexual scenes with her (not all implemented but the starting split for the corrupt and non corrupt version of her story is in).
Glad you liked Elora shutting Leandros down. I really wanted to emphasise the player choice there in effecting if Elora gives in to the worry and fear of if her anger wins out over it, and especially show if you don't give in to him El isn't just going to take this lying down.
That Charlotte route sounds like a bug. I think I'll have forgot to remove the through effect on Cam's movement when leaving meaning you can walk through everything but not interact with it on touch as you're always moving through it. I'll get that fixed now. Thanks for the spot and report.
For the items they do currently have uses. The axe can get you access to a secret area, and the blue orbs there are 4 of which give you access to a hidden area, puzzle and quest.
The rusted key and area behind it will hold more quest content and rewards in the future so for now its more like early exploration. There are a few hidden areas I've yet to add full rewards too as I plan on relating them to quests or items ive not implemented yet in 0.2.
Finally, the Duke Raymonds content ends after his dinner for the moment. El's maid work, Cam's viewing of his collection and alternative ways to get inside as Cam, will be coming in future versions (Some already in the next one).
