I've never ever dabbled in patchremi, and I think after playing this I might check out a doujin or two. Im hooked.
I really enjoyed the story and the characters. With remi being protective and worried over her flan, and gaining patchy's trust as the story goes on. Flan being a little silly gal despite the circumstances. And patchy being patchy. I also really like the dynamics, obviously with remi and flan. But, patchy and remi interacting with bickering or regular conversation and getting comfortable with one another throughout is something that I didn't know I needed till now.
The music was a nice listen, the art was cute and had a style that I enjoyed, and (keeping it brief to exclude spoilers) the setting/story was a nice take on a backstory. Really enjoyed the game!
