This is really quite good and I enjoyed it a lot; the mixing of Greek mythology with Japanese mythology with Christian mythology was a bit weird, but the story set pieces showed a lot of originality and actually invested me in wanting more.
Three suggestions:
1) It wasn't until approximately 50% of the way through playing that I noticed that some scenes play / have animations after text and pressing the space bar (to get to the next dialogue) skips them. VN players are conditioned to mash the space-bar to move the story on, you need to stop them from doing so if you've spent the time on scenes. So, please give a visual indicator that a scene is about to play so that players don't skip them! Up to that point I was a bit... well, mystified why there were dialogue gaps / lack of exposition etc.
2) Pick a penis model & stick to it - the MC started off with a rather upward curved look (original and unusual to see) then moved towards the "straight plank 4x4" model. Personally, the curved model worked better.
3) At the moment it doesn't appear that skipping scenes leads to alternative paths (I only tested this a few times so maybe it does?), it'd be a good idea to again tell the player if it's a pure skip or if there are multiple possible paths.
But anyhow: really quality little VN atm, would love to see more.
