This was pretty great. I liked the characters and writing in general; world building was, in my opinion, really well done. I like how the NSFW aspect is presented and well justified: it feels like an integral part of the mechanics of the game and the story. It's all really nice. Congratulations!
The in-game animations are well done, the full screen illustrations, and the graphics in general, are all really charming. I love the character portraits!
The "there was a pretty bad jam" dialogue section is so ingenious and funny to explain why the ship is empty. I liked the humor, and even though the game is funny, you can still feel there are serious themes being explored.
The mechanics of the combat sections of the game were interesting and well realized, I think. It would be nice to see this expanded in future versions.
There's a lot of polish here!
Now some critiques / suggestions:
The font chosen is a bit hard to read, at least for me.
I feel like maybe the initial dialogue with Eelili gives too much exposition at once. It is narratively justified, as you are controlling an amnesiac — however, I feel it is too much information to absorb at once, and it would be better to learn more of it progressively through the game.
Also, I felt like some things could be explained in a more concise manner, especially during the tutorial. Maybe it's just me, though! And, again, this doesn't mean I didn't like the writing, which I did! And, it's also all optional dialog, and you can read it at your own pace, so that's good.
I also think that the text for the cutscenes maybe went a bit too fast for me (I'm kind of a slow reader). I would have preferred to be able to click or press a button to move to the next text, instead of it being dependent on a timer.
But, overall, really great and ambitious project! I would love to spend more time with the characters and discover the rest of the story!
