Let me start of by saying that I absolutely adore the art style. The visuals and atmosphere are downright beautiful.
Some constructive criticism though - a lot of older point and click adventure games do this thing where interacting with an object once does nothing, but interacting with it several times makes progress. This is pretty iffy from a gameplay design standpoint. I didn't figure out the acorns until I looked it up in the walkthrough, since clicking them didn't do anything I assumed I was missing some kind of tool to reach up there. There's not just the issue of figuring out you're supposed to spam them, there's also the issue that this incentivizes the player to spam click every interactible object further on in the game in case it does something different than single clicking it. It sets a precedent, you know? And having to spam click everything just in case isn't fun.
There's also a minor issue where a lot of sex scenes sound like they're coming from the left offscreen, even if they're onscreen or off to the right.
I hope I don't come off sounding negative, this was a really fun play so far. I think the core gameplay formula is rock solid - a lot of porn games frontload a bunch of story or long-winded repetitive gameplay as filler between sex scenes. Tales of the Moon is just as complicated as it needs to be, no more and no less. Great pacing, too. I hope to see more criss-crossing paths going forwards, where you have multiple objectives you can do at once so you don't get stuck on the one specific task you need to do to progress.
I'd like to support development, but I have some reservations about giving money to patron what with that whole political escapade they got going on. Have you considered setting up a SubscribeStar as well?
