Isabel has good character depth, personality, and the writing is quite good. She was quite charming, which is something I rarely find in this category of games. This game would stand solidly alone, without the NSFW content with minor story tweaks (and a new basic plot), and I'd enjoy it too.
The NSFW parts have really nice art for them, and the writing's really solid there as well!
Humor is good, well placed, and not over-the-top.
Easter eggs are fun :)
Going to be looking into and following this series closely now!
===Bugs I ran into===
Playing on latest firefox, windows 10. BGM volume resets whenever a new bgm clip starts. This is doubly odd, as the selection does *not* reset, even after a page refresh.
The [Config] button also only seems to work once the text is finished typing out, unsure if that counts as a bug.
Might want to add a [Config] button to the main menu as well.
Attempting to change text speed softlocks my UI
The third time I reloaded the page (from the softlock mentioned above), the game failed to load. It worked fine the first two times. Shift-Reloading (Reload, refresh cache) and it loaded fine.
