Wish you would start including changelogs already, every time there's an update I have to look through everything to see if anything changed at all.

"The darn Game gets better in all aspects the further in you get and soon you are getting all sorts of fun things to do while playing."

Which means you have to do a whole lot of boring crap before it actually gets good. Smoke effects that hide the porn, But Thou Must, long, empty corridors with nothing to do, justifcations of porn that are about three times as long as the actual porn and the bizarre clusterfuck of Chapter 3.

As a game, it definely fills up its niche it tries to cater ( mind control/corruption, parasites, M2F, dominant vs sub choices )


The new updates are definetly an improvement in terms of story and consistency over the old versions, in the old versions the chapters felt a bit of rehashing part of the story just to be able to fit in more things, the narrative is much more fluid now and overall gives a better experience, altought the jump from chapter 2 to 3 still feel a bit jarring to me. I think you should add an extra page of text inbetween which talks about an aggression towards you, which is interrupted by the awakening sensation.

One slight annoyance from my side, is that with the new chapter 3 structure, you lose the 'race against the clock' that forced you to solve a puzzle to infest youself and other to different patterns to avoid being discovered, you can SORTA still do it, but when it's voluntary it kinda loses its meaning; I can sorta understand why you'd leave it out since several play for the smut alone. Perhaps you should consider in the future to add a difficulty mode, which would reinstate that; perhaps add other difficulties too, for those like me that don't mind an extra challenge


That all being said, as the author also admits, it introduced a sleeve of bugs due to the reworked mechanics;


Some that might be worth mentioning:

Starting as chet, when you reach chapter 3, even infesting yourself with starfish parasits will never let you max out your breast size, this because you start with 0 and the code checks for 

if $people[$name].lactation < 10
set $people[$name].lactation += 1
set $people[$name].breastSize += 1

this implies that breast size will only be bumped up to 10 from the starfish, but to reach full size it'd need to reach 18, it's better if you increase them independently like this

if $people[$name].lactation < 10
set $people[$name].lactation += 1

if $people[$name].breastSize < 18
set $people[$name].breastSize += 1

this has a rather nasty consequence later in the game, because if you don't reach full size, you cannot infest your breasts with werms, which in turn if you infest your brain you cannot fight back, locking yourself to the submissive choice.


Another weird thing is that in chapter 3 after you infest your brain, the message from your master still speaks about incapacitating the ship's crew, i guess you forgot an if check.


In chapter 1, tracking infestation for the player in regards canal parasite permanency for the player seems to be broken, as in it's never triggered.

In chapter 1 also, it seems that even if you cure yourself of all parasites, before turning yourself into a female, if you launch the pod, it acts as if you're still infested and doesn't let you skip to chapter 3.

If you let yourself to transform to female, cure your infestation, and skip to chapter 3 using the escape pod, you'll get no chapter begin text about the dream awakening, and you'll start as female as if you chose it from start.


When interacting with claire, in chapter 3, all the parasite actions seem to send you back to home, unlike when infesting other chacters.


You should add a button to reset the audio, sometimes when meeting a bug between events the music gets started, and going back in the browser results in both musics playing at the same time, muting would mute both, it's frustrating if one wants to preserve music playing, even just stopping the songs without restarting should suffice since sooner or later you'll meet a scene trigger which will start a new song, so silence would be brief .


And finally, not a bug, but a reccomendation from my side:

You're making a picture for every permutation of effect, so you have a picture for starfish infection for the main char, one for starfish and mouth canal, one mouth canal and no starfish, etc.

This is extremely inefficient, it means that for each character you need to save 1+2^bodyparts pictures, so 1+2^(canalmouth+starfishbreast+canalvagina+canalanal+vaginawerm) = 33 pictures per character ( in practice it's going to be a bit less considering that pose will let you skip some, but it's still going to be a large number ).

If instead you separate each body modification part as transparent picture overlaid on the base one, you'd need to store only 1+canalmouth+starfishbreast+canalvagina+canalanal+vaginawerm = 6 pictures per character, moreover, the game logic is going to be simpler too since you'd be only toggling the visibility of the overlaid part individually, and the pictures themselves are going to be smaller too since being mostly empty, the compression will be highly effective.
