For the first two issues you bring up: the state of the demo and keybindings mentioned in the menu.
1) The demo IS iffy. When it was released, we did a pile of bugtesting internally and thought we had a stable version, however when it went public both with the advanced paid release and the free version, we didn't get any feedback or complaints for a while so stupidly assumed everything was good. So we continued with a major update for the new enemy character models. When bugs started to get reported, we tried to rollback our version control to do fixes but found it broke lots of the game. Even resetting back to where we had progressed to caused files to break so we've been stuck only able to go forward and get the new update done.
We've implemented user testing on Discord and so far we're on about test version 4 with a hefty pile of bugs outstanding still, but the hope is that once we get stable we can fix the dodgy demo.
2) Keybindings in the menu have been fixed and updated. My only excuse there is that when things got changed I forgot about the options menu.
3) Character models are updated so the LOD issue is gone.
4) The dungeon lighting not so much. I'll add that to the buglist. However we're planning on updating and changing the dungeon in a near future update.
5) There's been some updates to FPS. It turns out that if you don't set an FPS cap, Unreal just tries to go as high as it can, so the different quality settings now enforce the FPS cap they say they should stopping GPUs from just spooling up and shooting out of the PC case.
6) The softlock sex stuff is mostly the major bugs I mentioned at the top. We've got a new sex system as a temporary solution, though I am planning on totally overhauling the system for a lot more interactivity/gameplay during sex.
7) The plants are supposed to be spottable. It means that players can lure enemies into them, and you don't just suddenly get caught by something you had no way f spotting in the long grass. However, I have found that when you start getting chased, plants are often missed when running until you run into it...
I can't say when we'll be getting the next version out as it depends on getting a stable version, but I do appreciate the feedback.
