Honestly, this is a pretty great visual novel. Seriously good job Double Moon!
The gameplay revolves around building energy or spending energy to influence the decisions that the main girl makes. Which in turn influences how much she likes you and who she builds relationships with.
The scenes play out in different order if you don't influence her, so your decisions change the flow somewhat. And some repeatable scenes can change if she likes you more.
Version 0.8.5 has no endings so you can keep improving your relations with everyone, though I suspect that will change once they are added in later. Because there are no ending in this version, you can work towards all H-scenes of which there are a lot! The game also runs really well on my potato computer :)
If I could make a suggestion, adding a gallery would be nice for revising old H-scenes or seeing variations of the same H-scene. That would also be a good reward for multiple playthroughs when endings are added in.
Edit. Forgot to mention, exchanging 10 energy to remove 1 occult is probably not balanced enough since Zoe can easily earn back 5+occult points in the late game.
