For your first commercial game, it's got charm to it. I checked out your patreon and found the pricing to be odd, in tandem with the Itch.io minimum price to unlock the game. $8.88 to unlock the game on this platform, but your prices on Patreon are, $3.20/$6.20/$9.20 monthly.
With a pricing scheme like this I'm curious if this project will be regularly updated on Itch.io as new versions release or if it's going to receive quarterly updates or any at all due to being on Patreon for a lower price.
I'm optimistic that you will be adding more content/polish to the existing game, in it's current state its missing certain elements to it that make it more appealing, such as a gallery, or way to interact with the H-scenes during the game.
In short,
You're doing a good job, just a couple of odd details that can be easily ironed out. You're potentially on your way to something good :)
