TLDR: Comic great, "game" presentation needs a lot of work.
As a comic, I'm not going to comment much on it. It's 18 pages long, quality artwork, decent story, the girl looks a little derpy, and one sex scene (no nudity thankfully). Maybe the colours + lighting look a bit flat, but that's about it.
However, "Paradise Slice 02: Read the Comic" (also Slice 01) is technically considered a "game", or rather, an interactive piece of software which centers around this comic, not too far off from most e-book readers, and from a technical perspective, it's incredibly barebones. You can click either side (or arrow keys) to flip pages, pop it out to another tab, and nothing else. No music or sound effects, no additional flair, nothing that oozes "creativity" aside from within those pages.
Here are some suggestions for improvement:
*** Try to add stuff from the author comments (descriptions, credits, links to other comics, etc) into the software itself.
Example: The instructions could be a single pop-up when you open the comic.
*** Visual indicators that only show up when you hover your mouse over one side (to indicate you should click to flip the next page.
** Display 2 pages like a real comic book
** A short animation that plays when you flip a page, rather than just instantly skipping to the next page.
** Some music (that you can change volume). Maybe 2-3 different songs in different sections of the comic.
* A button to jump straight back to the start
* Change the title from "Read the Comic" to just "Comic", preferably in brackets
* Some voices / dubs if possible.
Hope that helps.

EDIT: Do note there's a difference between something being barebones and being minimalistic.
